fuel regulator problem

[winkdogydog101]

ok just wondering my friend and i got the same fuel regulator off ebay and his is perfect on the dot at 40psi. however mine keeps droping and losing it pressure? I do have a bad 02 sensor could this be why im loseing pressure? im not 100% if its just mine is a POS or if the 02 sensor is making it run rich which is why im getting a leaner reading on the fuel regulator.

THANKS GUYS

Your o2 sensor has absolutely nothing to do with your fuel pressure regulator. Once you set the base fuel pressure it's set and will only change with boost/vacuum. It sounds like you might have gotten a POS.

really thats what i was thinking shit well i was wondering what peoples thought of the sard fuel regulator on ebay where sard is name brand but it looks a bit funny its for the evo 3s so it should fit\

SARD Fuel Pressure Regulator Kit for EVO 1-3 DSM 4G63: eBay Motors (item 350359456839 end time Jun-25-10 22:09:16 PDT)

what if my vacume is ####ed up or something like that?

Not worth the money when you can pick up a new 2g or EVO one, bolt it on and have rock solid fuel pressure. There is no need for an aftermarket regulator unless you are looking to lower base fuel pressure. If you have something to tune with to compensate for the added fuel pressure, I would highly recommend running to your nearest dealer and grabbing one. They are less than that SARD one.

ahhhh shit like a stock one? for a 2g? or evo which is better? and i have a 255 fuel pump i wanted consistant fuel pressure. But i ran it on my stock one and my stock one ran it fine so idk whats going on.

But a eprom can change my fuel pressure with the stock regulator
