Has anyone had experience with Dahl,Davco,Racor,fuel water separators. What would the min flow rate for our HPCR trucks be. Thanks in advance BIGNASTY
 
you can make a vastly improved setup using two wix 24770 bases and a 33374 filter followed by a 2 micron 33674 i am going to paste a reply i gave to some one.



we mount the filters just forward of the fuel tank. we run a fleet of dodges and recently installed one on a 06. there is two bolts through the floor board for a rear seat option at this location. some of our trucks use them others do not. get a 2" x 3" piece of angle iron 6" long. make a card board template that the two bolts and keeper nuts will go through hold the template on the inside against the 2" part and drill the two holes they will be about 5/8" i think and about 3 7/8 " between. center the holes on the 2" and near the edge on the 2" hold the angle iron over the bolts with the 3"part the further est away from the tank and drill a 1/4" hole between the two holes, keep drilling through the floor board. now after you mount the filters to the angle iron just simply mount it with a 1/4 grade 8 bolt. this is the only hard part the other items is easy. the total time including building the bracket is about 1 1/2 hours. i will give you napa numbers but they can cross reference to wix or car quest. the two bases are 4770 the water separator pre filter is 3374 the 2 micron filter is 3674. use a 3/8" nipple with about 1/2" space in the middle connect the two bases together observing the in and out. because of this the mounting plate on one filter base is about 1" further out than the other. install two 90* 3/8" barbed fittings on the bases and temporary bolt the angle iron up and hold the filters up to it. make sure every thing clears and mark the one base that touches the plate to drill the three holes to mount the filters. next cut the feed fuel line at this location and bend the lines out a little and install 3/8 hose over the lines and to the barbed fittings. i put a small amount of flair on the steel lines. but i do not think it is necessary. bleed the air out through the stock filter before trying to start it. use a gauge and do not change the filters until you see a two pound drop this should be about every 125,000 miles and the stock filter will never need to be changed.
 
BigNasty,

Most of our trucks are specced with the Davco's in various flow rates depending on the size of engine. I have seen then on medium dutys with a 5. 9 Cummins.

I will try to get you a link later today or tomorrow.



They should be mounted where you can easily see them as the fuel level in the clear top dome indicates when the filter element needs to be changed.



We have had very, very good luck with them and one feature that we really like is in the event of a failure (cracked cover or similar catastrophic event)on the road you can remove the dome and element, then there is a threaded stud on the base that accepts a Detroit Diesel or similar spin-on to get back home.
 
Thanks I didnt know about the spin on filter. A truck driver at a fuel stop had one and we talked about it he didnt know the spec's on the filtration part but said it stops a bunch of water. He went on to say that he ran the same I 5 trip to Tacoma and back every week and before he had the Davco installed he never had much water to drain. After the install and at the same fuel stops he was surprised about the amount of water.
 
Here is a link to get you started. This would the size needed for a 5. 9L. Any truck dealer should be able to get one of these should you decide it's for you.



Forgot you yesterday, very sorry. :eek:



Let me know tomorrow if you have more questions, need a rough idea on pricing or whatever.

Have a question the 243 I think that was the model has a max of 60 GPH the 382 has 180 GPH I have an AD 100 with a flow rate of 100 gph I know that allot is returned to the tank but the Davco is before the pump will the 60 gph get sucked dry or not be as efficient? Or should I go with the 382 ,can you have to big of a unit because a mech where I used to work gave me 2 382's they dont need them they have no trucks.

I am no expert on fuel flow but I don't see why the 382 could not be used.

If you have room to mount it, that is.

I have a link to the 382 filter elements and if you get the 2 Micron version(Fleetguard FS19761) that should be what matters.

Maybe someone far more savvy with flow rates and requirements than I will chime in.



AH64ID is up on it judging from some of his posts, maybe he is on tonight.

I dont know if BIGGER is always better in some cases I have to ask AH64ID or go to Cummins they sell the same thing with their name on it
