A buddy of mine and I replaced the fuel pump today. We didn't get it totally done today because it started to snow heavily, but all that needs finished is the lines hooked back up to the sending unit and the patch panel screwed in.
We ended up cutting a patch panel in the bed. We were going to dump truck the bed...but my 1/2 to 3/8 reducer snapped so we couldn't undo the bed bolts. Then we were going to drop the tank but the jack I have didn't reach...so we just said screw it and cut the bed. It's not a pretty cut since we drilled holes and took tin snips to it, but it works I guess and i've got a set in bed liner so it's not too big of a deal.
Someone had been in there before me in the past to change the pump because one of the metal pipes on the sender had been broken and they had just used a longer length of hose in it's spot, but unfortunately the sending unit was still factory and one of the fittings was so rusted on it broke instead of coming loose so I had to replace the sending unit as well as the pump. We will see tomorrow when I finish hooking everything back up if that did the trick.
