Just use the same fittings that you have hooked up to the injection pump. Its the same. Shorten the line and hook up the stock between the filter and IP...and you are good to go.

Thanks Dan, Can tell me what pressure I should have on my gauge (before the cp3)

150/95-XXXX pump should be in the 13-15 PSI range.

Ok maybe I'm missing something but the stock supply line for the tank goes into the stock lift pump. the pump is mounted on the stock filter housing there is know fitting after the pump it hook the Fass supply line too. know I haven't the removed the stock lift pump, is there something under it that I'm missing
thank
Jeff

You need the adapter to go in place of the filter mounted lift pump.

Good catch....for some reason i thought he had a 98.5-02...but yes..you will need on of our FP-1001 filter plates to take the place of your stock lift pump. You might call a FASS dealer as they might have a few extra. The kits for the 98.5-02 trucks come with one but its not used.

I just read this thread (and a couple of more) and I am getting ready to go to a FASS pump on my 2002 with in tank lift pump that I think has either quit or is real weak - I think it might have been a factory LP replacement but it was on the truck when I got it. I also have an aux LP frame mounted between the tank and the Injection Pump wired direct to battery through a switch and a relay.

I have a few questions.

Is there any advantage to keeping the stock fuel filter in place - I know a lot of people by pass it. It seems like extra filtration and water seperation would be a good thing. Any down side to keeping it??

One thread seemed to say that the FASS is designed to let fuel bypass the pump but go through the FASS water seperator and fuel filter when the pump is not running.

Did I understand that correctly?? I want to keep the existing frame mounted LP as a spare and as a way to easily prime all filters after I have changed them out and if something happens to the FASS have a back up to continue on by just turning it on.

So if I put a"T"' in line from the tank to FASS pump line, run the main line to the FASS pump intake side and another to the aux intake side and another "T" from the aux exit to the Fass intake side(creating a loop) it should work to prime both the Fass Filters and the stock filter because it will let the aux push fuel through the FASS filters to the stock filter. Correct?? If I do this should I put in a shut off on each side of the aux LP to keep fuel from pushing through the aux when it is not running or does it matter??

Finally if I use the stock filter I just run the FASS exit line to the stock filter housing and up grade the line size/banjo bolts from the stock filter to the Injection Pump to ensure I'm getting plenty of fuel to the IP.

Am I tracking.

Thanks.

I feel running the stock filter head is redundant and not needed. Even in the winter if you run the correct fuel and add the appropriate additives.

EH....well i would plumb it just a tad different if you were going to go that route. AND You can make this as simple or complicated as you want.

If you wanted to mount a "Spare" pump...i would plumb it in series with the pressure fuel line, but isolated by 2 ball valves. (Ill see if I can draw a VERY crude flow schematic) You would also need a 3rd in between the 2 valves to keep from having pressure and suction mix (Unless you used 2, 3 way valves...that would work better, just make sure they don’t cause restriction).

Then on the FASS, you can leave the FASS in place and allow fuel to be drawn though it, or make a by pass line with 2, 3 way valves to allow removal repair if needed.

• The small black squares are the Valves. The medium square is the CP3 or VP-44
• The big gray square is the Tank.
• Small red square is your aux pump.
