Yesterday I got at it. Had about 5-10 gal of fuel still in the tank. The fuel line connections at the top of the tank can be a bit difficult for those of us with large hands. The complete job took me about 2 hrs by myself. I lowered the tank on some wood blocking and just walked it down to the ground and just the reverse to put it back up. I repaired the sending unit by cutting off the plastic stud and then installing a p-nut on the metal shaft. I also bent the contacts a bit so they will still work if it developed more play. I did notice that the float was starting to break up on some of the corners, has anyone else noticed this? Overall it is a pretty simple job. I don't know how you would do this by lifting the bed if had no one to help you. Now we will see how long the repaired sending unit lasts. Cheers
