LS1 FPR Problem?
Has any one had experience with the fuel pressure regulator on the stock LS1 rails going bad? Is it even possible for it to go bad? I'm assuming it has a diaphragm like a regular vacuum regulated one but I really don't know how the stock LS1 regulator works....is it possible for it to be replaced or do I have to replace the complete rail setup? Any info on this would be terrific....
