Aftermarket FPR's?

So whats the deal with these? I mean theres not any to my knowledge and im sure theres a good reason. So i wanna know that good reason lol. Im guessing the stock 4or whatever psi is good? The main reason i ask is because of the power level im at.



I remember someone said one time that there is a stock replacement part...maybe acdelco...that gave them like 6 extra psi.

GP Sorensen is the one people go to. I wished I could tell you the reasoning, but I can't remember. If you go to clubgp, search for Sorensen, filtered by author Mithelen you should find the part number and the reason why it's the preferred FPR.

GP Sorensen 800-302

Most of the old GM FPR's I have seen have a 1/16" diameter return hole though them. The GP Sorenson ones have a 1/8" diameter one. If you are using a high volume pump, the small hole regulators can cause pressure to creap up at idle and cruise due to too small of a hole for the fuel to return through. The GP Sorensone ones also tend to be about 2 PSI higher base pressure (arround 54 PSI)than the GM ones (around 52 PSI), which, if you are on the edge of maxing out your injectors will help extend them a little further.
