I am looking at adding a lift pump to my truck, and was wondering what the best bang for my buck wound be. I’ve been looking at the fass 95 gph pump but I am not sure if that will do the trick? I am pretty much have my truck the way I want it excepted maybe a bigger programmer. Does anyone know the HP limitations on the 95 gph V.S. the 150 gph?

I believe the 95 should suffice for everything that you need. Unless you are going to be running a larger turbo or bigger sticks, the 95 will work with the largest programmer you can find.

Do you see all of the results that they clam with these fass pumps or is that just something to reel you in to buy there system? Also would the 95 support the addition of the aurora 3000 or would that be reaching the limits of the pump?

Yes, I think the 95 will supply all the fuel you need with an A3K. As far as all the claims. it does remove water from fuel, it will help a fuel starved motor increase high rpm hp, it will eliminate most causes of limp mode, P0087's and such, and it will help to eliminate air entrained fuel if you use the FASS system with filters.

The 95 gallon per hour pump will empty your fuel tank three times in an hour. Unless you run such a huge program and injectors that causes you to find a gas station every twenty minutes it will work just fine. (I doubt that it is even possible and if it is would the engine handle that much power for that long of a time period?) The fuel that you do not use is routed back to the fuel tank and is just traveling around getting warmed up and full of air. Not ideal. Don't fall for the "Bigger is Better" in this case.

The 95 pump is more than enough unless you are looking for more than 600 rwhp ...

by the way,
thanks again for the very nice install - service and everybody there at Huckstroff Diesel that work on my truck to install the FASS unit!

Fass 150/95 on mine, works good for the past two years

If your going to add a pump, you might as well add the bigger fuel pickup.
just my .02

FASS 95GPH here....no fuel pickup needed on this truck:)

i should be in the ball park of 600rwhp

Shop '06 Dodge that is at 600 RWHP is sporting a 95 GPH with no probs.

The Advantage of a FASS is extremely helpful on the D-Max Trucks. It polishes the fuel by running returned fuel though the filters. This means, Like John Stated, that you will filter a 30 gallon tank 3 times an hour with the 95 GPH pump. ALSO with that returned fuel, is the removed air that is being sent back to the tank. This will promote injector life and give you a 100% charge of fuel in the Rail for injection. Another added benefit, which im really preaching to the choir here, is that the CP3 pulls fuel from the tank on the D-Max. We put about 8-10 PSI of head pressure to the inlet of the CP3 to keep cavitation from occurring. (I wish yall could see the air being sent into my injection pump on my VW Jetta. It has a clear line and you can just watch the bubbles go by. Injector Pump pulls fuel from the tank not unlike the D-Max.)

The HPFP doesn’t give you the filtering advantages, but it will give you the same rock solid pump off the FASS to keep pressure to your CP3 under high demand situations.

With my FASS 150/95, my fuel pressure gauge always reads 7 - 8 psi, is there any way to adjust the Fass pump to push a solid 9 - 10 psi, or am I just stuck?

UM......well.....i might have an options.....but i have never tested that combo in a Chevy pump before....

I get 14 PSI on my pump with my PS-1002 Spring in my Dodge....but that is apples to oranges.....BUT the CP3 is not much different than the VP-44 in my truck as far as how our pumps dead head and flow through.....SO.....

I would think if you ran a PS-1002 spring with a 0.010" machined return fitting...you might see 9-10 PSI.....but im guessing....don’t get a lot of request for pressure that low.

Might I ask why you want just 2 PSI higher? From my talk with the CP3 guru's, its not going to do anything for you. BUT PM me and lets see what we can do…..

I had read in your post about 8 - 10 psi, so I thought since mine was a little below that, there was setting that I could bring the pressure on up to 10 psi.............not sure if that would be benificial or not. I tried to PM you, but it said you didnt accept PM's.

Does the fass systems change the economy + or -?

Thanks for the info, just put the order in for my pump yesterday.

You can mess with different springs, but I don't think you will see any big changes though. If you go too high with the PSI the CP3 will not like it. What adding a lift pump does is push fuel into the low PSI side of the CP3 each and every time that the CP3 is trying to suck fuel in. Sort of like a McDonalds shake that is being shot into your mouth instead of you having to suck it up through a straw. Much easier that way.:D The end result is that the low PSI side of the CP3 has a full charge each and every stroke. The high PSI side will then use what it needs depending on the demand at the time. Without a lift pump the low PSI side of the CP3 can not keep up with the needs of the high PSI side under higher demands put on it from higher HP tunes.

I would not think so.
