I Finally replaced the fuel pump and sending unit assembly. I got some tips from members to remove the truck bed but I had the bed spray lined last year and couldn't do that. My gas gauge was not working so I decided to take it out. This is not a real bad job but it's easier to have some help. I did it myself and it was not fun. As you can see from the pictures, the float was damaged by the sending unit arm. It looks like the wire that wraps around the float cut a hole in it. Too bad because the sending unit was still working. The pump was original and it's a good thing I replaced it anyway. One thing I found was the rust that dirt and grime was causing on the frame. This dirt is trapped around the tank and stays wet all the time. The pump assembly cost $95.00 and it took me 4 hours to do it myself.
