tech charlie has installed my 350 out of the monte into his z28. we have bypassed the sensor for the oil pump to cut off the fuel but we can not get the fuel pump to run without wiring it to the ignition directly. so what he wants to do now is go back to the manual pump. when we were using the electric pump we had a fuel regulator on it. he needs to know what he has to do to the tank to run the manual pump.
