the 24v is max of 17
get your facts straight before spilling them
and as for the fass system it is a great addition to the truck or an airdog[/QUOTE]

Agreed The first gen 24v at much over 18psi turns out deadly for the VP44 my buddy smoked his down thata way.. and My opinion in seeing alot of these cummins or any Diesel engines fuel systems Airdog 2 is about the only way to go for a reliable fuel supply :tu:

Were talking about 12V's here - for a street driven truck this is absolutely not true. IMO, the stock pump is more than adequate for your everyday driver.

Tune the afc?

Ahh sue me. Musta been tired. It's not the fact that 24v's need a LOT of fuel; it's that the vp44 needs CONSISTANT fuel. Whereas the 12v's arent finnicky like that.

I agree. I just messed up my reasoning haha. The vp44s need consistent fuel or else they burn out.

hey bud just lettin you know if you steer someone in the wrong direction it can cause bad things just research somthing is all i am sayin

No I appreciate it actually. I knew what I was talking about, I just wrote somethign other than my brain was saying. I know its not so much the high fuel pressures that matter with the 24v; it's the inconsistency of fuel that kills them. Hence, an airdog helps worlds on those and not 12v's.

thank u that was so helpful! thats what i had thought about the air been in the line it would work its way out. on the pump what sucks is i just bought the pump becaus i plan on changing out the injectors and maybe trying to pull a few ponys out it and the other reason was we couldnt get the fuel line that my machanic that helps me wanted to get and with the fass it came with it and for the cummins pump was $365+shp so it was almost as much as the fass and the fass holds up to 600 so if i deside to go bigger i can and not have to worry about fuel i guess. do u think the ldle could have anything to do with it?

An OEM lift pump is less than $100.

Yes, if you dont have 750 rpm in gear bump up the base idle. Wouldnt tell you to do it - if I dont think it would make a difference.
