If this were the case wouldnt I be loseing oil to the fuel system. I,m not exsperanceing any oil lose or any sign of oil in fuel. I,ve looked in the tank. I would also think I would see some kind of back pres when I did my fuel pres ck. Thanks anyway. Votran John. PS You do make one validite point. Maybe Its not so much a high spike as a droop before the spike. I.ll have to regraph my condition.
Your right If the top Oring goes bad Icp pres Blows back to the crankcase not the fuel system.
