Thanks for the reply. Last summer I did buy a fuel pressure gauge and checked the fuel pressure while it was surging, but its worth a recheck. After reading your reply, I went out to check the fuel pressure regulator on startup, but something must have fallen off of my fuel pressure gauge in storage because it no longer pushes the poppet in on the fitting on the fuel rail. I'll have to go by Harbor Freight and see what I am missing out of the hose. One of the disadvantages of buying at Harbor Freight, but otherwise I probably would not have a fuel pressure gauge. I did take off the vacuum line and there wasn't any fuel or fuel smell.
