Well, after 7 years my primary pump stopped working. I dropped the tank down and was shocked to see the power wire in the fuel pump assemble got so hot it melted its own insulation, fuel pump socket and a piece of the gas tank baffle! The harness was getting 13.8 volts at idle, grounds were excellent and everything was done right including relay. Had no issues for about 7 years. The secondary pump still works. I am wondering if the primary pump wire is to thin to take the 13.8 volts?? i doubt it though. Any comments??
