Well after a long wait I now have a few of these kits ready to ship.

Racor 2 micron filter with lift pump, water sensor and heater. Comes with frame mounted bracket, fittings and hose. Also has its own control unit and the pump can be used to prime the filter and the OEM as well. RTeplacement elements are not in yet.

I'm a little confused. Is this the new kit that Racor has come out with for the DMAX, or is this a kit put together by Lube Specialist?

how much?........what psi to the ip?.......filters not avail?........what other applications used on?....how many inlets ?........internally pressure regulated?.......Internal bypass?......or make your own?........do you have one on your dmax?....got lots of questions...nice switches

Excellent, there is a lift pump!


Ditto what sdaver said. http://www.dieselplace.com/forum/smileys/Big Smile.gif

The whole kit is $350. Replacement elements should be in in the next couple of weeks or sooner. It will deliver a max of 10psi. Has internal regulator and bypass. One inlet and one outlet which are 3/8 npt. As far as other applications I can't say for sure. Racor has had this unit out for a couple of years now.

Greg....


Is the pressure adjustable? What setting do you recommend for those of us with a post OEM Mega who are having to bleed ours every few hundred miles? Is it wired to begin pumping as soon as the switch is cut on (glow plug position) to ensure flow when the key is then turned to the crank position?


JimEdited by: JEBar

Why the pressure pump ? Added resistance? I take it we're putting this before stock filter. That's great, 10 micron filter should need changing once a month if thats the case.

Is this the same setup that GM is working on as an option? Sure would like to have the GM stamp of approval.


JP

Anyone planning to run the lift pump continuously? This pump seems to be intended for occasional operation, I wonder if it has the strength/durability for continuous operation?

This pump is made for the application we are wanting. I have talked to one of Racors engineers and he says it will work fine. But I guess if you asked another it won't be OK.

Greg

Very cool Greg!


The switch bracket says prime. So is it really a lift pump or a priming pump? I would *guess* that a guy would think it was primarily for priming rather than a lift pump, but that would depend entirely on one's interpretation of what the switch really means.


Are there any specs on filtration and flow rate?


R, Steve

Yes it is primarily a lift pump but withthe switch you can use it to prime the filter as well. The elements that I have in these plus the replacements are 2 micron. Flow is rated at 50 gph.

Thanks Greg!


From another thread, I also recall some talk about pumps introducing harmonics and thereby causing less fuel filter effectiveness. If you get a chance, could you ask that Racor engineer if this is addressed, or is even an issue, with this application?

Its my feeling that in this application that its not and issue. You will have it mounted quite aways from the pump. George Morrison and talked a lot about this very thing.

Greg

I think this filter is a slick idea and I'd want to run it continuously. I'm just wondering how an integrated pump's vibrations would affect the filter media's effectiveness. I agree the vaccum pump would be well isolated from this pre-OEM filter installation.

I really don't think its and issue because its not high pressure.
Greg

Is this the kit that RACOR and GM have sanctioned, or, not? As I recall the RACOR/GM kit did not have a lift pump.

No its not.

Greg

Any word when the GM approved filter kit is coming?


JP

Greg


Is this pump adjustable so you can provide zero pressure at the test port?? Is the filter in the system before the pump?? Are there filters available that are less than the 2 micron rating??

Does this run all the time or to check prime / lift? Again are we putting this before or after the factory stock filter?

ok im a idiot when it comes to this kinda stuff, what in the world does this do for the guy who doesnt pull, just runs around town and takes his wife and dogs for a ride?

Larry
No the pump is not adajutable but you can order it set at any pressure you want. Youcan also get 10 and 30 micron filters. The engineer said the pump was after the filter but I am not so sure about that after looking at it.


Topgas
It will give your engine cleaner fuel for longer injector life.

The way I understand this we should be shooting for as little positive pressure as possible at the test port. I know the guys with the homemade systems are using a bleeder setup to allow adjusting of the pressure. How would you adjust the pressure of this pump to avoid over pressuring the system??

Greg,


Is this pump a flow through design.

Yes the engineer told me it was a flow through. That way if the pump quits you will still get fuel.

Larry,

Looking at Greg's picture of the RACOR pump/filter (nice! http://www.dieselplace.com/forum/smileys/Cool.gif), it looks like it would be easy to add a bypass regulator (per a bear's design). Just add a tee to the input and output of the filter and bypass fuel (output to input) through a needle valve. Adjust the needle for 0 psi at the schrader valve test port on the engine for approx 0 psi. This would be basically the same as my lift pump set-up ( http://community.webshots.com/album/77018086bLHHHC) except the RACOR pump/filter is one unit. The RACOR flow through pump design is also a plus (like the AC pump I used).

Pretty slick install!!! Helps with my next step.

Tom, Thanks for the feedback. If you decide to add a lift pump feel free to contact me via PM with any questions... I would be happy to help if I can.


I also checked out your website, goosedowns.com vey nice! http://www.dieselplace.com/forum/smileys/Clap.gif


My daughter is a horse person.. She's been riding for 10 years since she was six. She works at local ranch with about 30 horses that looks similar to yours.

............I just had a RACOR 445R (R90S) fuel filter (pre OEM) installed yesterday under the hood just above the power steering pump. Hopefully it will stem the tide of dirty fuel out there. The mounting bracket that is black was custom made and it is attached at the left via 2 tapped holes next to the A/C compressor. Also if you look under the bracket you'll see a brace attached to stop vibration and add further support. The filter, in turn, is attached to this black bracket. I breathed a sigh of relief to know I didn't have to mount it on the frame under the truck. This location makes it way more accessible to service and drain the water from the seperator Here are a few shots of the installation.................................Steve ...

Thanks! Most days it is great fun around the horses - today it is 29 and windy, so not so great out. We have 45 horses, 6 months to almost 30 years. We have quite a number of young people who ride with us, and it really can develop character in people. May be my legacy.


I'll be in touch after the weekend, as I have to be in Boston for a meeting, and thins on the ruck will go on hold for a minute. At least I have a 2 micron pre OEM.


Tom

Is there anyone interested in buying my Racor
660R2 filter assembly (with new 2 micron filter) for $65 ?

I want to upgrade but I've got another 5000 miles before I remove the assembly......

You made one mistake with the install. The clamps on the hoses by the yellow plastic ends will cut the hoses and actually make the hoses weaker. The barbed ends dont require clamps. It actually voids the oilguard warranty if I use them with those ends.

Thanks for the tip I just removed the clamps. ........Steve...

Shuffman...

Depending on how tight you got those clamps you might have already damaged the hoses. They work on the chinese finger trap principle and pulling on them makes them tighter. If you cut the inner weaving of the hose they have lost the ability to get tighter. You might want to just replace them.

Actually the dealership put the clamps on which I thought was strange. You would have thought the mechs would have known about those push lock fittings. They were installed Monday and weren't clamped on that tight so hopefully they'll be ok. I guess time will tell........................Steve... Edited by: shuffman
