Has anyone heard of the diaphram going bad in the AEM Fuel Pressure Regulators on a consistent basis? I just bought an AEM fuel rail for my h22 and the only FPR that can go on it is the AEM part# 25-303 FPR, but this dude is telling me that he has already gone through 2 of them on a stock setup.....?? Anyone have this problem? Should I go with AEM FPR or Not? I have a B&M on there now that converts the OEM FPR to an adjustable one but I think mine is going up too.

 

I have heard of that, but mine has been fine for about a year now......except for when I broke the nipple off. Personally, I wouldn't think you'd have any problems with it as long as you have a FP gauge and you keep an eye on it.

 

Cool, thanks, I'll go ahead and try it out. I figured they cost so much that they better work without being defective.
