fass??

[mike77]

new to the Forum looked around a little before posting this and havent seen it brought up yet.

little background: I have a 2010 F-350 4700 miles on it. volant intake, cat/dpf delete M.B.R.P. stainless exhaust, and a spartan 275 tune,
when i go anymore then half throttle my fuel pressure gauge on the piller reads like 1.5 - 2.5 PSI after i did this once or twice I though it would be a good idea to drive it as easy as i could until i got this fixed.

question: could this be something wrong with my stock pump? bad fuel? or do i just need to put a FASS system in?

Thanks

Are there any codes? The stock fuel system is more than enough for the 275 tune.

[outlaw351]

yeah i would def. say the stock system is plenty also

[mike77]

no codes when i talked with spartan they said the same thing anyone else have this happin i dont really wana spend 600+ if i dont have to but i will if its going to be better on the truck

If you do take the plunge and get an aftermarket lift pump, go with an Air Dog II. I would definitely be sure though before you spend the money. You should be maintaining at least 3 psi with the stock low pressure pump, so you definitely have an issue.

Air Dog has a better warranty (lifetime) and they use 1/2" fuel lines, FASS uses 3/8" fuel lines. The filters on the Air Dog are also not big and bulky like the FASS ones.

It must be something recent because it hasn't always been that way. I think it use to be a 2 year warranty that FASS gave out. I guess they realized that daddy's business was selling more units.

Fass has always been a good product, but the air dog system has just refined the technology just a bit further in my opinion. Are the fass systems still pretty loud compared to the airdog? I havent heard a new fass system in the last year or so.
