factory unit or aftermartket? very vague question, the diaphram may have torn or a have a hole Ive heard that china copys use very poor material which fuel will eat over time
what symtoms brought you to the this conclusion? Its a very simple device that should not fail uner normal circumstances what makes you believe this?
i believe this because i just put 15 dollars of gas in my car not the cheap gas
and i was driving and the car just cut off then i tried to start it and it just kept cranking over.
when i got the car home i replaced it and the car started right away
and every time i replace one it works for like 2 weeks then just stops working out of no where

OK do some basic testing first check your fuel pressure this will tell you if the FPR is leaking or faulty are you sure you are refering to the FPR? pics please
Monitor your fuel pressure that will tell you what your FPR is doing or not doing also I HIGHLY doubt its the FPR its a VERY simple unit I leaning towards your Fuel pump it more likely to fail before the FPR even a new one what brand and where did you get the fuel pump theres china pumps going around for quite some time now they look like genuine walbros
Also do the 12v fuel mod as well to help isolate the problem,Did you drill out your j-tube? That will make you fuel prssure spike if you are running a 255 pump.

Think you're on to something... could be too much pressure from the pump, ripping the FPR a new one.
