Nobody has any ideas, i have never had a bad regualtor before so not sure if this could be the cause as the pump is on a relay so it shouldn't be a problem you would think......the pump puts out 11psi and they bypass opens up and the fuel pressure reg is set for 6.5 psi so why should it go to 11psi unless something is wrong with it....dirty sticky or whatever........like to hear your opinions.........thanks
