i have a 390, not sure on the year, in my 68 ford. its my daily driver now for a little less then a year and im on my third fuel pump. does anybody know what would make them go out like that? the one that came with the truck quit last december, and the other one quit in august. when they were first put in the truck it would start right away for a few weeks, and then not so good after that. if i floor the gas pedal right when i crank it over it starts pretty good.
