Same, did not openhttp://www.dieselplace.com/forum/smileys/Cry.gif

Do you have a cost?


I got it to open earlier and printed it out at that time.

MSRP is $410, some distributors discount off that. I just ordered one and the distributor is putting in a 2 micron filter in place of the 10 micron.

Sometimes you have to post a link to a page that has the .pdf on it in order to gain permission to download. The link goes to a dieselplace upload page with the .pdf indentified, but I still can't get to it.

$410 TOO MUCHI had a quote for $165 with the 2 micron and heated bowl. Although I wiuld have to find the connectors but for $245 will pay for several hours of my installation time and the time to find the needed parts.http://www.dieselplace.com/forum/smileys/Big Smile.gif





Patrick

I just finished talking with my GM service manager, and he has no problem with me having any fuel filtering system installed. Hearing this I received a quote for $155 for the kit and $205 for a heated kit. I know that $410 is a bunch of money, but I believe the GM kit has the heat and the WIF sensor that ties into the DIC to warn you of water in fuel. Still not sure that is worth an extra 200 bucks. I'm probably going to go with the a different kit by Racor.

Is this the long awaited GM approved fuel filter kit??


Where do I order from??

Well I got the .pdf file, thanks dmax lover.


Called Racor.


She said the kit number is good, but not available. $410.00 suggested retail. Gave me a number for a distributor in the Salt Lake City area, they're out of business.


She also said the filter guard, I'm one of those four wheeling types who's trucks get off the road, does not show up on her computer.


This is not good for a company like Parker Hannifin who makes quite a bit of aircraft stuff that works pretty well, to be handling Racor like they really don't care about what's going on. Maybe that explains the delays in this kit coming out, or more specifically the whole inadequate filtration of the factory system.....http://www.dieselplace.com/forum/smileys/Ermm.gif

I asked this question in another thread." We all agree there is water in diesel fuel,then why do we never find water in our filters when we change them?" I always drain my filter first. There should be water in the bottom if the separator is working. Maybe there is just no water in our fuel. I DON'T LIKE CONTRADICTIONS.http://www.dieselplace.com/forum/smileys/Angry.gif We need a grrreeeaaat fuel filtering system and we need it quick.

If you took a sample of fuel and had it analyzed, the results would show dissolved water present. This water does not come out with water seperators nor do we worry much about it. It's free water that creates the real problems. Most of that gets handled by the seperator. When using a second filter you have two seperators.

Okay boys, here's the dope straight from Mike at Racor engineering....


The kit was developed in conjunction with GM. It plugs into the existing wire harness, comes with all the fittings, hoses, etc.


It's also a 10 micron pre-filter. Racor says the OEM filter is a 2 micron........http://www.dieselplace.com/forum/smileys/Confused.gif


Now based on what I've read here, I'd gotten the impression that the engine mounted OEM filter wasn't that tight, but this guy was a straight forward type who knew all about this thing and I gotta believe he knows what he's talking about.


So yeah, it's spendy, but it's got to be the most funcional setup with the ability to work with existing wiring and the DIC, WIF, heater and site bowl. The 10 micron pre-filter followed by a 2 micron final filter is exactly what's needed.


I'm sure this will start some conversations about the veracity of Racor's claim, I'd be interested in hearing them, but I'm really skeptical now.

Well, it comes back down to if you can get the big rocks out first, the stock filter will perform better. Progressive filtration, plain and simple. If the finer filter isn't plugged up with big pieces, isn't that more area to filter the fuel, thereby increasing its efficiency?


On the other hand, put a more efficient filter with larger capacity first, and you can achieve the same thing. Oh wait - that's been done...


Seems to me Racor is making good sense here. I've seen and worked on several different types of fuel filtration systems on boats, trucks, and cars, all diesel, NONE of which had a fine filter first in line. Always a larger (10-15 mic) primary, followed by a (>= 5 mic) secondary.


Bear in mind that I currently am running ONLY the stock filter, with plans to install the MEGA pre-oem, once time permits. Practice what I preach? Not always. Just my .02 that Racor is perhaps on the right track, and either method works...


Ty

Is this the long awaited GM approved fuel filter kit??


Where do I order from?





I have one on order from oregon fuel injection - they contacted racor right after the first of the year (at my request) and have several on order for their stock. First one in goes on their own duramax, second one goes on my truck; third one...??


www.oregonfuelinjection.com (http://www.oregonfuelinjection.com)





I forget the exact price - a shade over $300 I think...


They have been very responsive, ordered some stanadyne additive from them and it was on my doorstep the next day... (it's only 100 miles from my home).


jeff

Well Racor has the exact kit that I sell but only they have added the WIF. They have the same bracket design, location everything. I am now in the process of putting together the very same thing and I can tell you it will be a lot less than $410. The heated kit I have know is half that. I will be posting picture of the kit in the next day or two. As far as using a 10 instead of a 2 I will be using a 2 micron. They OEM is such a peice of crap that i want the best filteration possible before the OEM. I know this goes againt all logic but sometimes things need to be done that way.

Greg

Greg,

Can you get us the wiring harness connections, harness, etc. As my kit is now on the way from you, what do I need to add. Install instructions for those of us not the sharpest mechanical tool in the shed would help also.

Greg...I was just thinking about your kit on the way home from work today. The Racor looks to be the same as yours, with the addition of WIF and heat mated to a GM approved harness. As asked above, can you provide the Racor wiring harness that connects to our trucks?

The wiring harness will not be Racor because non of this is available from them yet. I have had my distributor working on this for the last 2 days and they are telling me that its not available. But this is very easy and I am going to be making my own.

Greg

Seems like 10 micron might be too much and 2 micron might be too restrictive -> I'll probably compromise and go with the 5 micron option (they make 2,5 10) with the 60 series filter - if I can fit a 90 series unit with sufficient protection and ground clearance - I will go with 2 micron.


jeff

I personally don't understand the logic in 2 WIF sensors. Let see ... trucks come new with 1 deficient fuel filter with a WIF sensor. If you get enough water in fuel to trigger the WIF sensor wouldn't it be detected by the OEM WIF? Why 2? I understand detecting it earlier ...but water is still in the tank/fuel. I'll stick with my "Greg" kit with the 2 micron I've been running for 5 months.


On edit: I would be interested in the shield/bracket if it protects the filter however. http://www.dieselplace.com/forum/smileys/Big Smile.gifEdited by: tophog

Racor only makes 2, 10 and 30 micron filters. The R60 2 micron filter is not restrictive at all. A new filter only has a .05 psi drop accross it.

Greg

A new filter only has a .05 psi drop accross it.

Greg


At idle or WOT? The R60 should only be able to maintain 300hp based on its rated GPH.Edited by: Amric

That is at its rated 60 gpm.

Greg

How is this thing plumbed into the fuel lines?? It looks to me that the kit requires that you CUT the primary fuel line coming from the tank. I wonder if the General will be OK with that from a warranty perspective?? Yes I'm being sarcastic http://www.dieselplace.com/forum/smileys/Evil Smile.gif Logic would dictate that any debri produced as a result of cutting the line would be caught by the OEM filter, but I can just hear the Regional Service Rep..... Warranty denied, you messed with the OEM fuel system. Really sir, this is a GM approved system??? Please PROVE it to me and I'll think about not voiding your entire warranty.......... Oh, you put it on yourself..... Well seeing that your not "MR GOODWRENCH" then you can't possibly have a clue how anything mechanical should be done.... WARRANTY VOIDED!! Have a nice day.





OK, enough of my rant about GM. If someone can produce a GM document (ie a TSB) that addresses the fact that this is a GM approved system AND it is OK to cut the fuel lines AND (big and http://www.dieselplace.com/forum/smileys/Dead.gif) does not require that a GM tech install it, then I'm getting in line for the Landry system

My take on this would be if Racor does not have a piece of paper saying"install of this filter assy can void your GM warranty"than Racor could be held responsable for damages.I would think that Racor being the mfg of the oem filter, they would only do this with GM approval for liability reasons if for no other reason.Remember they are attaching this to GM electric's as well.GM could cause major grief for Racor if they did not approve of this.But it would be good to hear what Racor and GM have to say.

Has anyone heard whether this system is going to be offered as an after market install by GM dealers, if so I don't see how they could void warranty's, of course Ive seen them try some pretty sneaky stuff.

Bulletin states see Racor dealer or GMC dealer for installation.





I also ordered from oregonfuelinjection. Its listed on their website at $307, free shipping.

I would be very interested in seeing it available through my local Chevy dealer's parts counter. I know it will cost more, but the way I view it, there would be no doubt about it being blessed by GM that way. I always get a discount on purchases there anyway, because my dad is a dealership retiree.


I usually hang out at the Chevy garage on Thursday nights while I'm waiting for my daughter at scouts, so I'm going to give the printout of the "Racor Product Bulletin" to the Parts Manager and see what he knows or can find out. It states on the bottom to "Contact a Racor distributor or your local GMC truck dealer for installation and assistance." so I'm willing to see what can be done in this area.


After all this reading, I'm convinced that additional filteration is probably a necessity, however I'm confused as to which is best. I'm also concerned about GM's blessing on added filteration. And I'm also concerned about our Michigan climate and what adding a second filter will do in terms of fuel gel and a plugged filter. Personally, up to this point, I haven't fiddled with fuel additives and I don't want to start now.


I'm at 9990 miles this morning and picked up an OEM filter a couple of weeks ago with the plan of changing it at 10K. I've made the slight "adjustment" to the A/C line per dmaxalliTech's instructions and just need to pick up a bigger filter wrench to change it this weekend. In making the "adjustment" I found that the A/C line was stiffer than it appeared, and between 1/4 and 1/2 inch of movement allowed the necessary clearance for the new filter to drop into place. It will be interesting to see the inside of the original filter after I get the new one on.

If anybody is interested in the Racor RK 32313 I ordered from a place called CLF in California. Give Bob a call at 800 479 3608. He is willing to substitute a 2 micron filter instead of the 10 micron also, at a very competitive price.


Hoss

FWIW- I took my truck for a tire rotation this morning. I was talking to the service manager about additional fuel filtration, and showed him the racor product bulletin about the fuel filter kit just released. his words were that racor makes a lot of filters for different applications, and this may not be a bad idea, but he also said that after installing this there could be warranty issues, if a gm rep had to approve any fuel system repairs. I said it looks as though this is gm approved because it ties into the DIC info. he said unless a product is specifically sold as an aftermarket item by gm through the dealership it would not qualify to be gm approved or recommended. his advice was avoid fuel system problems was to change filter often, and by fuel at high volume diesel fuel stations, and avoid big name but low volume stations.

Again another service manager that has his head up where the sun don't shine.

Greg

Here we go again......even the GM approved stuff gets the "reject" button. They must teach them this stuff at the training schools "always reject repairs under warranty if there is anything not OEM on the vehicle. We can always approve it later if the customer complains, this way 75% of the people will walk away or pay for the repairs without questioning us". The other 25% complainers we will fix it, but add 2-3 days to the shop time to punish them for daring to second guess us".

Surely Racor could/should shed some light on this?!?!?!?!? It is only in their best interest to divulge whether or not GM has put thier blessing on this. If they have gotten the General's blessing - then they should be more than willing to give us the details. I, for one, will not ASSUME that because it happens to interface with the DIC, it must be GM approved.


I would really like to get the scoop from either Racor, or better yet, GM. I think I will drop Racor a note and see what they have to say as well.

Talked to local GM Parts guy this AM, he had no clue,
and called GM, they in turn had no clue. Suugested I send him
the link, and I believe I will. My take is simply this
it seems to me that this was released too early, and
neither Racor, nor GM is prepared for either the initial
demand or questions. I talked to Oregon Injection, and
the facts are that they do not have stock, and the delivery
they expected was not made. They are trying to get a date
for a real delivery. They have gone from needing 4 kits, to
10, to now 20 kits. Obviously there are several of us.
In my case my service manager suggested that if this kit exists
use it to avoid not just issues with fuel filtering, but
also to avoid warrenty issues with the wiring harness.
Frankly, I am pissed because like all of you I spent in excess of
30K for something I am putting more, and more safety
features on. We should be spending this money on
programmers, beer, tires, and women, not fuel filters, etc.

...It's also a 10 micron pre-filter. Racor says the OEM filter is a 2 micron........http://www.dieselplace.com/forum/smileys/Confused.gif


Is that what the OEM filter is, 2-micron?

Its funny that Racor can't produce the kits. I will have them ready to go in a week or so. All I had to do was add the WIF and wire harness.

Greg

Is the Racor kit installed pre or post?? Why can't we purchase the Racor kit, (not the GM version) our selves and do a self install?? Much cheeper to do it your self. Finally, why not copy the harness, put it up on the web and we will make it ourselves. Or someone can copy it and sell it to us.http://www.dieselplace.com/forum/smileys/Approve.gif

Greg Edited by: chevmeister

Sent e-mail to Racor requesting clarification on the RK32313 being GM certified.


As far as the OEM filter being 2 micron - that was not my understing. I thought it was a 7 or 10 micron? Could be wrong - but it could be verified pretty easily.

Something's not right with this bulletin. It states:
<BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px">
Racor filter 660R210
Max Flow 90 gph / 341 lph
Max psi /kPa 30 psi / 207 kPa
Element R60T
Drain Self venting
Heater 12VDC 200 watt
Water sensor Dash indicator
Filter guard RK32347</BLOCKQUOTE>
The 660R series head is a 60 gph head not a 90 gph as stated.
If it were a 90 gph head, it would be a 690R Racor designation.http://www.dieselplace.com/forum/smileys/Confused.gif

A couple of weeks ago I stopped by the Chevy store to talk injectors with the diesel guy. The sum of the coversation was: "yes we're seeing a few problems", "yes extra filtering couldn't hurt" and "when you get your kit, bring it by and we'll install it".


Today I took the truck in to get the tranny serviced, so I took my new Racor pre kit by to show them. The service manager and the diesel guy/shop foreman were standing together so I presented the kit to both of them. They were very impressed and wanted the info on where I got it. They had heard the rumour about the GM kit but they don't know when.


I let them install it. They were a bit pricey but at least I know they won't give me any grief about it.


Truck has 48K on it. I hope I didn't wait too long.

The 660R series head is a 60 gph head not a 90 gph as stated.
If it were a 90 gph head, it would be a 690R Racor designation

There is only one filter head for the 645, 660 and 690 series racor filters. The difference is in the filter element. Has to do with rated flow capacity. Your correct in stating the max rated flow for the R60T filter is 60gph. So there seems to be an error in their literature.

Did anyone get reply's on their requests to Racor on GM's position on this set up??

How many GPH does our truck require?

How many GPH does our truck require?


I think I remember that "racor" stated that stock filter was something like 47 gph... I'll see if I can find it...


jeff

No response whatsoever from Racor. Kinda makes me think we could have a couple of problems on our hands:


1. Maybe they do not check the customer support e-mail mailbox very often (at all?).


2. They a "a person" that is responsible for this type of customer question and he/she is on vacation.


3. The conspiracy theory - they are sandbagging us trying to capitalize on our concerns over the fuel filtration on the DUramax and really have no intention of even to mentioning this to GM let alone gaining their endorsement.http://www.dieselplace.com/forum/smileys/Evil Smile.gif


I put item 3 in there just to stir the pot!!!! http://www.dieselplace.com/forum/smileys/Clown.gif I know that will push of couple of you guys' buttons.... http://www.dieselplace.com/forum/smileys/Big Smile.gif


But, from a professionalism standpoint, it would have been appropriate for them to at least acknowledge they received the e-mail even if they did not have a formal response yet. And this WAS sent prior to the all the e-mail worms that surfaced last week. Oh well....either way, the Duramax requires some form of additional filtration regardless of GM's admission of the fact or not!Edited by: BKG-22

How many GPH does our truck require?


Here is one way to get a rough GPH estimate.

With the DIC set for instantaneous MPG I have noticed single digit values when accelerating.

For example assume 5miles/gal at 60 miles per hour…

(60 mi/hr) x (1gal/5mi)=12 gal/hr

When I was initially looking at supplemental filters I found that most of the choices were in the 50-60GPH or higher range.
http://www.dieselplace.com/forum/smileys/Geek.gif

From Racor...


"The maximum rated fuel flow through the DMAX OEM filter is 48 gph."


I was just looking at Bronco's post on rev-limiter, etc. Is 48 gph enough to satisfy the peak fuel needs with mods? I wonder what happens when this is exceeded - does it fail or constrict?

http://www.dieselplace.com/forum/smileys/Geek.gif





I was just doing "back of the envelope" calculation to guess-timate how clean the fuel gets after driving a while since the majority of it is recycled back to the tank (after passing through the filter) - much is sent forward from the tank to cool the injectors, etc. I was guessing that 1/4 of the fuel gets "polished" per hour on a full tank - more as fuel level is depleted.


I have seen it stated that the majority of the fuel is sent back to the tank - a SWAG at it would be 12 gallons per hour per your DIC guess-timate plus at least 13 gallons per hour flow back to the tank. So total is at least 25 gph for your guess at actual flow??


So with mods - rev limit moved from 3200 to 4400 rpm - if it were a linear relationship then flow needed would be greater than 34 gph. That's assuming same amount of fuel delivered (stock versus modified) at a given rpm, which it isn't...


jeffEdited by: dmax lover

I have also tried to contact Racor before via e-mail. It has been over 1 month with no response. I basically complemented them on my past experience with other products they manufacture and explained how I did not understand how they could fall so short in the Dmax arena. I asked for a explanation and explained I was open minded and very sckepticle of the naysayers. I provided a perfect oppurtunity for them to defend themselves. I guess they are above that? On the "page" they had an emplyee that floated around. His post are still available.

I also posed a question to Racor when I was designing my engine mounted filter. They responded to my question with a BS answer. When I asked them to elaborate they did not respond. This is one of the reasons I don't have much faith in post about what Racor said. Later! Frank

Wow! $410 for the filter alone? How much is installation? I have been looking at the Megafuelfilter kit. It is 2 micron and about 4 times the size of the Racor. I found it on GMCs home page. it linked back here to Diesel Place Forum. this url; Yuck I misread it,http://www.dieselplace.com/forum/smileys/Dead.gif Its not this url its


www.thedieselpage.com/reviews/megafilter.htm (http://www.thedieselpage.com/reviews/megafilter.htm)


At $230 It looks a whole lot better than $410 and GMC obviously must feel its appropriate in that they link to it.Edited by: Captain Butch

Well the Racor kit I have is much less than $410. I have a range of Racor kits from $160 to $285. PLug and play and can be installed by anyone with a bit of mechanical ability. Comes with all the needed hardware and wiring harness if needed. No holes to drill and the only special tool needed is a compact tubing cutter. Installation is from 30 minutes to one hour. If you were up my way $50 installation. You can see the lastest kit.
