Would there be any negative affects of putting on a competition lift pump (GFS-392 ) with a mainly stock truck? Also if I put it on without any real mods to my motor, would 35ish psi going to the cp3 damage my cp3? Would I see any gains? like mpg gains. ( I plan on making hp in the future but im just getting all the small stuff out of the way) thanks

Your in-tank lift pump fuel flow is good for close to 500 Hp.
I have never seen anyone that claims a power boost from adding a aftermarket lift pump run dyno numbers before and after installation on a factory pump that can support up to a given number. After a given number than a aftermarket pump comes into play.

This does not relate to the engine mounted or filter mounted electric lift pumps as they are peices of crap.

then my stock 06 with a 65hp quadbox is making over 500hp. cause i cant suck it down to zero if i stay in it to long.

Your cp3 will be fine with 35+psi, however, your stock fuel filter canister probably will leak like a sieve(sp?)... You have to keep pressure 25psi or less, to be on the safe side. I see 20psi mostly, except on the really cold days it bumps up to around 25psi.

btw- before my Walbro, I'd suck the fuel pressure down to ZERO with just the xzt box and that's why I added the Walbro...

35 PSI would be a great way to remove the lid on the fuel filter canister. Check into the billet lids from Geno's. They are very nice.
