Anybody know where I can find a replacement cap for the fuel pressure test port. I ?fumbled while trying to put it back on and it slipped down into an irretrievable place. I'd like to get a metal cap if possible.
Was getting a rich bank 1 and 2 reading and was trying to troubleshoot it. For the mean time, took the vacuum line going to the fuel pressure regulator and moved it from the throttle body (where it didn't seem to be doing much) to the manifold vacuum. Dropped the fuel pressure almost 20 psi, car runs OK and exhaust smells nice and lean again. Just need to get the check engine light off for NY state inspection.
