My Dad and I both have Durmax diesels we just discovered this web site and have trouble getting away from it since it is winter and outdoor activites are minimal now.


We have been looking into alternative filter systems besides the Nicktane. The Nicktane looks really good, but we came across the RACOR unit. Any users? any comments?


I can see it would require cutting some pipe but we were quoted a install on the Chevy Durmax aprox $250.00 parts and labor.


The filter retails for about $125.00 not bad at first glance.


Any comments would be appreciated.


Have a Merry Christmas

diesel biker, considering the quality problems people have seen with the OEM Racor (rust, one guy actually had his come apart internally), I personally trust the Cat filter more than anything made by Racor. The Cat filter is a well engineered and superb quality piece. They actually built their own automated factory just to produce it to their quality standards. Plus it's a large filter (the 1R0749 anyway) so you can get some reasonable life even filtering at 2 microns. And it's not overly expensive, I think I pay like $17 each for'em at the Cat dealer.

One thing about the Cat that I don't like, however, is the packaging. They just toss it in a cardboard box, it's not sealed in plastic like the OEM piece. We're talking about awfully small particles here, and a cardboard box is not the cleanest of environments. I've noticed quite a bit of small particle debris on the things right out of the box, around the threads on the clean side for example. BUT ... since I've got it installed pre-OEM, I don't worry terribly alot about that. I wouldn't want one post-OEM though.Edited by: ZFMax

I've run the Racor 660 using either the R60S or R90S 2 micron filters. I bought as a kit and installation was simple (about 10 minutes). I get the filters via the Internet for about $19/ea. The Racor has the clear bowl and drain... think you can also get with heater if you need it.


On edit, I also think based on fuel analysis the Racor setup has turned in some excellent results.Edited by: tophog

As a group, we have tested most of the supplemental fuel filter systems available. Reference the data contained in the PDF file at this link:

On the thread mentioned by Dmax Affair above, you will see a picture of my Racor filter installation also. Listed below is a picture of the kit I purchased and the price list.

Besides the Racor filter set-up, Kennedy also sells a filter set-up also which is based on the Baldwin filter. All three will do the job (Cat, Racor or Baldwin).

The filter that I have not seen mentioned since I found this site is the Amsoil/dahl. It has a water seperator and drain on bowl plus filter cartridge is available in 10 & 2 microns. And they are available in 3 sizes.


Anybody seen or tried one?

hddm3, I'm at 75,500 miles on my 2001. But I only installed my Kennedy Megafilter post-OEM at 73,600. I'm hoping that it will carry me to 100,000+ since I've had no issues so far.

I installed my Cat at 8,000 but only hav 19,300 right now. It'll be a few years before I see any real benefit(or lack thereof) but hopefully over the next few months more people that drive a lot of miles and have added secondary will be able to chime in.

ZF MAX--------I'm glad your OEM filters are wrapped in plastic. The one I just bought from my dealer was'nt wrapped in anything---just came in a card board box with the 'O' rings in a small flat plastic envelope--------------------Phil

Victory Red,


Did you ever move your Filter to the 'high side'? Think I told you that I have mine mounted on the engine block above the Power Steering unit. Used to have air about 2x a week, since I moved it, not once.

Mitchagain,


Yes I did move mine. It's much better, but after 5 or 6 days I begin to get a "rumble" when first started(fuel starvation). No stalls since, but I may need to shorten my fuel line run. I currently have them running around back over the turbo. I think the shortening the in/out fuel lines may help my situation.


There is air in the system, and in my case I'm thinking when the air builds up and the lines run a little 'dry', the pump can't catch up to fuel filters in time causing my 'stumble'. Hard to say, a lift pump would take away this issue, but I just don't feel my talents are high enough to install one.

Got my pre OEM Cat installed at 2200 miles, have 5800 on the truck now, including a run down to Florida from Ohio. Mine seems to run very well and get excellent mileage. I think/hope I got a good one!


I chose the Cat for the ease of finding filters, the size of the 0749, and the price of the spin on elements.

VictoryRed,


GO FOR IT!!!



Considering the great work you have done on the SS tailgate support
, YOU HAVE the talent to install a lift pump. The Stanadyne FM100 with a lift pump option is probably the easiest and most economical option...

The Baldwin-DAHL is an excellent filter and it was discussed briefly in the original TDP fuel filter threads. I bought a DAHL-100 for my 98 K3500 6.5 TD and was planning on installing it on my DMAX but I decided not to and I sold it. The main reason I chose not to use it was that the 2-micron rating for the DAHL is a nominal rating – 50% efficient at 2 microns. The absolute rating (99%) is around 12 microns. All the various filters being used for the Duramax (CAT, Baldwin (MEGA), RACOR) are high efficiency filters - 98/99% at 2 microns which is what we need for the BOSCH common Rail system. There were also reports of vacuum leak problems with the DAHL on the Ford site. I don’t think it would be a good choice considering the high vacuum levels that occur with the stock DMAX fuel system. However, looking back I could have used the DAHL with a 30 micron element as pre- filter in front of my lift pump in place of the Stanadyne FM100. One major benefit of the DAHL is it’s superior water separator design. They are also reasonably priced. A few years ago I bought one with several spare elements and the heater option for about $120 from westfeet.com.

Victory Red,
IMHO there is no need for a lift pump on your type of install.I have my CAT 0750 filter mounted in the same location & have over 3,000 miles on it with no problems.I have towed my 12,500 lb 5er 1,000 miles over some pretty big mountains.
My hoses are only 3' long each & I made sure all my barb fittings were good & tite. Sounds like you have a minor vacum leak.

Chipper,


I've considered the fact I may have a small leak somewhere. I just have been busy on my other project to give anytime to that since it hasn't been an issue as of yet. I bought a new gasket for the primer cover a few weeks ago to replace, just haven't gotten that far yet.





As for the lift pump, the other benefit is keeping the fuel filters full of fuel in a post oem setup. All 3 filters I've changed out so far(1 OEM and 2 Cats) have have the banding which means that they aren't staying full. I just never liked the idea of the additional parts/maintenance of it. I'm starting to get a little swayed, but I'm going to play with this setup a little more to see if I'm overlooking a small leak somwhere.
