fuel pressure drops at wot
70psi at idle but as soon as give the truck wot run the pressure drops and will drop to zero if i let it. Just put a new upgraded airdog II on because i thought the pump was getting weak. Ive got the blue spring upgrade 6.4 banjos. What could cause the pressure to drop that low but only at wot? Im stumped.

Re: fuel pressure drops at wot
Have you replaced upper fuel filter, the airdogII is a new fuel conditioner/pump assy? I am assuming.
I have heard of guys having problems with pick up in fuel tank, may be where you need to look next. Does it change with a full tank of fuel?

Re: fuel pressure drops at wot
I wouldnt think it has a pick up ptoblem because im running a sump. New airdogII 165. And i changed the top filter. This is why im thinking airdog pump is bad.
