Quick question, what would cause fuel pressure to drop quickly after the pump turns off? It goes from 40psi down to 0psi in less than 5 seconds, and it's done this for the past couple years. When I installed the 255 last weekend I made sure the o-ring was still in good shape. I also have an aftermarket FPR. Any ideas?
