I think I may have a fuel pump crappin out. Need to know what you'all think. The f.p is set at 42lbs. w/line off and at full throttle it goes up to 60 psi. is this ok or do I need to get my hands on a new fuel pump. I have a walbro 307 now, was thinking about steppin up to a 340. need advice quick I have dyno pulls coming up this weekend.
