fuse 74

figured it out from diesel stop, earlier production models have a silicone gasket with a wire harness passing through it at the high pressure fuel pump, ford posted a t.s.b. for wire chafing and has produced a upgrade gasket with insulation over the wires, this is a serious failure disablig the vehicle, the repair requires cab removal, trucks built before 8/'07 are subject, t.s.b. # 7-26-2
