[QUOTE="03' White Snake, post: 16916239, member: 51916"] PPRV is a one way check valve. If it goes bad, your engine will get no fuel. That is all that could happen if it goes “bad”. Never heard of them failing though. Usually the line cracks or bursts and that is the issue. The point of them is to keep fuel pressure in the lines for a quick start up. If not you will have to crank for an extra 3-5 seconds or until fuel fills the line again. During WOT hits, the pumps are pumping lots of fuel, then you let off to shift, the pumps take a second to adjust, that is the hesitation you are feeling. No tuning is needed for a PPRV delete.
