let me say that the pump has already been bought and installed on my buddies 94, and i know he probably didnt need it, but he has it.

yesterday my bud called me up saying that he had a massive fuel leak coming out of the side of his prefilter/fuel heater assy. so i went over there and took a look at how it was setup, and i was baffled, b/c when the shop installed the Fass on his truck (150gph) they plumbed the fass to the fuel inlet of the prefilter assy to then run through the lift pump on the block then off to the injection pump. i dont see how or why they installed it that way, b/c the fass should be his primary lift pump. so rather than make him spend 300$ for the prefilter assy from chrysler, can i just plumb the main line from the fass to the inlet to his injection pump??? i know that ill need to flare the line so that it fits better to the soft fuel line, but is this the acceptable way to plumb a fass to the 12v's? TIA dave

 

In the two I've seen done the FASS went straight to the P7100 (180 gph I believe?)
The FASS for the 12V is a higher PSI set-up than for the VP so I hope the shop at least sold him the right pump but from what you described in their install I doubt they did?

 

We have two kits (Click for the install instructions):

1009 Kit

1010 @ 45 PSI Kit

Here is a chart to tell you which one is which....you can see the middle section that says "Utilizes Factory Fuel Pump". This will let you know which kits use the stock pump and not.

My guess is your friend has the 1009 kit that uses the stock lift pump. What i would suggest is to figure out a way to plumb it into the stock lift pump and by-pass around the fuel heater/prefilter if its leaking......

If its a 150 GPH kit, you cant get 45 PSI out of it that is needed for the P-7100. If its a 95 GPH kit...you can increase the pressure with no probs and go directly to the P-7100....

 

Here are two shots of the 150/95-1010 @ 45psi on my 1998 12 valver.

The first one is of the pump hanging out under the rear drivers side of the bed outside the frame rail.

 

This one shows the fuel supply directly from the FASS to the P7100 pump on the truck.

IF its the 150/90 or the 150/180 which are the 12v pumps,both at 45psi,then you need to bypass all of the factory fuel delivery parts,including the fuel heater and filter assemblies.These pumps create to much pressure to be used in conjunction with the factory system.One of the reasons these shop try and make this work is due to the injector return line not having a fitting as it returns into the top of the fuel filter assembly.All we did with mine was remove it,cut the end off with a tubing cutter,flare it and knerl it and reinstalled it sliding a hose which was T'd into the return off the p-pump.IF a fitting was made to allow one to bolt right to the end of the injector line on these two kits and instruct installers to use it,then shortcuts like this could be minimized.I will show a shot of what we did with mine.

I have had mine on now for about 4 weeks and LOVE it!.The pump has made a difference in how the truck starts and has smoothed out the motor also.It also has provided proper fuel flow to the P7100 and corrected my factory fuel line failure.I only wish I took photo's of how bad my factory lines were while we did this pump.On a truck which is kept as clean underneath as the top is my fuel lines were so corroded that when the tank was dropped they stayed up and di not come down with the tank to be removed.Many years of daily driving in the PA winter months had taken it toll and when we did the install we also ran a new return line.All in all a great product for our trucks.Thanks DPP!!!!!......Andy

The shots below show the fitting at the P=Pump and the way we tapped into the fuel return with the injector return.

 

Sense there is no way to contact Dan or FASS directly I will ask it here.I have a FASS 150 that was on my F250 when it had a 7.3 & was used as a pusher pump now with a 12 valve I would like to delete the mechanical pump & get the FASS to make 45/50 psi.Is there just a bypass spring that can be replaced to step up the pressure??
I know that you want to go thru your dealer network for sales but should have a way to contact manfacture direct,e-mail or phone.
I have had excellent service with my pump & hate to buy a HP fuel pump & add it to this one.
Thanks!!

 

Chris..
Which one of the 150 pumps do you have?.
Also if your original dealer did it correctly for your 7.3 then it should have more pressure than what is needed for a 12v as the 7.3 Fords used 60psi I think......Andy

 

Im guessing that you had one of our low pressure Ford Kits that worked with the stock frame mounted pump. If this is the case, you will need to plumb it in with your stock mechanical LP on the 12V Cummins. This is for the 150 GPH pump only. The 150 GPH pumps high pressure relief are set at 25PSI.

NOW if you had the 95 GPH pump, you can increase the pressure to 45 PSI with a PS-1013 spring. BUT this is all dependent on how old your unit is. We used to cut the high pressure relief in at 45 PSI for the 95 GPH pumps.....sometime last year we started running them up to 80 PSI for the relief.

 

Thanks for the quick response!! It, when run with a regulated return with just the 150 running makes 22/24 psi alone on a 7.3 . I do not want to run 2 pumps HP & a LP I just want to get the FASS up to 50psi & I can regulate it at the motor from there.The truck has made 780rwhp with the stock pump & some larger fuel lines & fittings/drilled banjo's on #2 only.Needs some more flow than the stock can handle!Can I send it to you for a mod or upgrade if I can not only change out a bypass spring? I bought this pump new in 05. Model #FASS-150 serial #1822.
Thanks!!

 

If its a FASS-150 Series...that dude was made back on 5-13-04. As it stands...that pump can only push 25 PSI max without long term issue. We can update it to what you need with just an easy pump change. Any of our dealers can help you with this uprate.

If it is a FASS 150...the part number is:

RP-1003 (200 GPH pump) = $325.00 + $50.00 core
And you will need a 45 PSI spring: PS-1013 = $3.00

 

Damm,that is not what I wanted to hear! The core charge is untill I send my pump back?I can just put my SX HP pump on it also but wanted 1 pump.
More money!
I will contact my distributor,you have been very helpfull!
Thanks!!

 

So far I have checked 2 suppliers that I use & no luck.


Update,supposed to be getting with ya!
