I sold my other truck, so I've got a little cash to spend on upgrades and was thinking about addressing some of the 24v fuel system issues first. I've already decided to drop some of the cash for a set of RV275s, but I'm looking for opinions/experiences with the FASS and Airdog setups versus a frame rail relocation of the stock carter lift pump (I've already got a spare carter laying around).

I am also very interesting in FS upgrade...I've a 99 24V... Why do you mention LIFT PUMP relocation?? Can have benefits mount LP on the rail??

I ran a relocated carter and then dual relocated carter pumps for about 15k miles... worked fine, but was always worried about them... Finally one died and I decided to fix it one and for all... So I bought a FASS 150/150 and am completely satisfied with my purchase

I ran two carters relocated to the frame. Not much increase in the way of longevity. So I went with a Walbro 392 from GDP on the frame and never looked back. Quiet and rock steady now for over a year. And a lot cheaper than a FASS.

My low fuel pressure light just came on What is cheapest aftermarket, I just ordered a stock from cummins today $118.00

fass, fass, fass the best thing you can spend your hard earned money on for the 24v. i love mine, get the 150/150, accepts larger filters than the 95,

bnold... your truck must run awesome. What are you getting for HP?

I have one too, but's it's stock w/245 HP.
I've noticed low fuel pressure recently... I'm going to get a FASS, but should I get a 150/95 or 150/150? I might get a tuner in a few months to add another 100HP. So I think the 150/150 might be too much for 350 H.P. What do you guys think?

you left out Glacier and other Walbro based systems, so the poll might have too many undefined "other"s.

Well you can put a bandaid on the system and run a stock style pump and take a chance on how long it will last or get one thats warranty for 6 years and gives you fuel and water seperation as in fass or airdog. Airdog is a more compact unit and had less issues and has been able to support higher hp with there smaller units in what I have seen. Plus there on sale right now.

I'll second the Walbro's. I'm very happy with mine. Super quiet and rock steady pressure.

Sorry, I should have included the Walbro and Glacier options--or at least lumped that option together as "frame rail relocation of a lift pump". I guess I overlooked them because I just hadn't really been considering the Walbro or Glacier kit route when I can get an FASS or Airdog for a few more dollars.
Does anyone know if you can edit a poll?

From what I've heard, the stock location of the lift pump on the side of the motor subjects it to extreme heat and vibrations and is a major contributing factor in the premature failure of stock lift pumps. Hopefully I'll get part of this right, moving a lift pump away from the motor and onto the frame rail gives it a more friendly environment to run (less heat and vibrations) and also changes the gravity situation for fuel movement by not having the fuel pump suck fuel all the way up to the engine compartment from the fuel tank.

I paid $119 on e-bay for a Walbro 392 with the install kit. That, plus some plumbing parts (Swagelok pressure relief valve, Jegs Y-Block for fuel return, etc.) gives me a great set-up for under $250. That's $170 less than GDP. I'm putting it on this week. My frame mounted Carter is a POS and puts out a whopping 10psi on the frame rail. Figure a 3-5 psi drop for distance and filter and you're getting nothing at the VP-44. I think that's why they put the stock pump at the engine, because it's so anemic....

can you post photos of the frame rail relocate PUMP...??

I vote for the FASS, because that's what I have. Going on three years and NO problems.
