I called the local parts store and they had first told me the truck was carbureted, which I didn't think it was. Then they told me the Fuel Pump was down alongside the Engine block. If that's the case than what is out of the top of the gas tank with 1 electrical plug and a main feed out and the main fuel return in? I have to know, she just shut off on me and the only way to keep it running is to use starting fluid directly in the air cleaner.
