Try this since you have the pump off. If you dont already own them go to any good parts house and purchase the quick-disconnect fuel line set. Then dis-connect the main feed line right behind the fuel cooler attach a hose to it and the mitusa hook up your drill start priming if the draw straw is the issue you'll def know it being that close to the tank if you get no fuel. If you find out the draw straw is the culprit order a pickup kit form ppe, alligator perf, or use a hellmann sump on the bottom of the tank I pefer the draw straw that way I dont have to worry about the line getting cut or ripped by debris on the road and losing fuel. keep us updated
