Thanks for all your replys The Dodge is 12 volts. The original pump is a 6 valve one and I have replaced the fuel line. I carried out a pressure test on the pump and it showed about 5psi. It broke down on the way to Damyns Farm. Got a towed by a chap from Felixstowe. (big thank you to him). stripped the pump cant see any fault. refitted it. got it going. Drove to outside of showground broke down again. Called RAC . We got it going again and he followed me 10 milesto home, no problem. So that is why I thought of an electric pump
