i was taking my car on a trip last weekend and was cruising and my fuel pressure gauge started jumping all over the place like 50 40 20 40. well i came up on stoped traffic and the car stalled, it started and got me off the highway. after letting it sit for a little the pressure came back up to 58 but would start to fall off a lil if i reved it, so i had it towed home on a flat bed. so it wouldnt strand me somewere else. anyway when i got home i took it down the road and under wot the pressure just starts dropping fast. Is this a bad pump or could it be something else, this pump is only a month old, because my first one did this b4 where the pressure droped under wot, and i thought i had it fixed by getting a new pump? is this just bad luck or is something causing it? any help would be great

check ur pressure regualtor it may b clogged, however it sounds likt the hose tht goes from the pump to the sending unit is either loose, or has a hole or some kind od slit in it and is leaking fuel back into the bucket....whn u changed out ur pump b4 did u overtighten the screw tht hold the hose to the top of the sending unit

i checked the hose when it first broke down before i had it towed bc the hose on my first pump tore twice around the clamp so it was the first thing i checked.
i guess its just the pump but still wondering what is causing it to fail

no u cant **** up ur regulator doin tht, ive done it alot, just make sure u put it back in the right way, also did u do any tipe of upgraded wireing harness whn u did ur pump? is ur pump overheating? when i did my racetronix pump i bought the wire harness as well cause a higher flowing pump requires a little more volts, do u have a voltmeter? i whould take a voltmeter to ur pump and c, if its low u could b a bad pump, it just seems odd cause like u said u just put it in
