I have never read about anyone installing a FPR when switching from the stock fuel pump to an aftermarket one. Is it necessary? I installed one last night in my car and i made sure it cranked and ran fine. Then this morning after about 10 minutes into my drive on the way to work the POS started sputtering and it died. It will not start back up. Am I supplying way too much fuel to the engine. If I put a FPR in the fuel line how do you regulate the fuel pressure or is it automatic? I could use quick suggestions as my car is stranded in the McDonalds parking lot. Thanks!
