Fuel pump replacement
TAKE THE BED OFF??? Wow, thats a lot of work. Two bolts with a jack underneath. Lower it down just far enough to undo the lid. Don't unhook anything. You can pull the entire setup out without the tank on the ground just keep it supported. I have changed three pumps by myself doing it this way. $100 for a Walboro 255 off ebay, do your research,. Not that you need that much flow, just an example, good luck, fairly simple to do.
Two bolts, one jack, 45 min,...just sayin
I'm not arguing about which way is better, there are a couple ways to change the pump, it depends on the amount of time one has to spend on it,..I was never on my back, I didn't get filthy dirty. If I had the resources like a place to set the bed, help taking it off, etc, I would have taken the bed off and sanded and undercoated the frame also.
They've got you over a little bit of a barrel since you had it towed there.
