BS! It be a pain in the butt, but you can change out the fuel pump on the side of the road. and really only a few thing holding the tank up so could just drop it and take it with you and fix it then put it back in. But first I'd check the pump, take a set of jumper cables hook them up, crawl under the truck pull the fuel pump plug and take the hot and negative and test the pump, gator clips works good for this, this will tell you if the pump is working or not to ensure this is the issue and not a break in the line from there. Gotta work from point A to B.
