I have a C&S belt drive pump with a bypass regulator that up until last week has worked fine. I went out to pack the track and the fuel pressure gauge was jumping from 0 to 6 to 3 and so on. I and some others at first thought that I had the fuel filter in backwards but after checking it, confirmed that I had it in correct. We then went out for the heat race (no hot laps at this track) and when I got on the gas the car just stumbled. It finally cleared out and ran o.k. Fuel pressure gauge did the same thing for 8 laps. For the feature I took the bypass off and I didnt seem to have much of a problem, other than fuel bypassing the needle and seets and spraying the hood of the car with fuel. I tore my bypass down and can't seem to find much wrong with it. Any ideas? Im thinking a regular ol mechanical pump may be in my future.

This is my guess. When alky, air, and aluminum get together they cause problems. What you see as a white power in some areas of the fuel system. I'd bet the white stuff has something stuck. WD-40 everything, from carb needle & seat to the fuel tank vent.

Thanks guys. I talked to Dennis at C&S and we are pretty sure the fuel we have been getting is corrosive and has something plugged or blocked. I think my fuel man is doing a little home brewing and passing it off as SUNOCO.

We had a similar problem earlier this year and after tearing everything down and apart it turned out to be the fuel p/u hose was collasping in the cell.
