    <font color="blue">If you drop the tailgate you can get to the nuts on the gas tank straps pretty easily. Soak them with a good rust penatrant and try not to break the straps. Also soak the fittings for the fuel lines at the top of the tank. Use line wrenches if you can get them so you dont round off the fittings. I just did this on my 89, any more Q's just ask

    if your tank is anything like mine was your sol. i had to get a new tank and sender because everything was so rusted it just crumbled. fastest way is put an inline electric pump on the frame rail and forget about the intank one. i had the luxury of replacing mine with the cab off the truck and it was still a pain in the butt. i suppose you could always cut a big hole in the rear bed and do it from the top. but still a major job.

    well i got it done in just over 3 hours...is that some kind of record cuz it wasnt all that bad?

    worst part was trying to balance the tank on my knees while locking that ring back in place that holds the pump and all that in the tank...

    3 hours isnt too bad at all. It took less than an hour to do mine but I didnt drop the tank. I cut an access hole in the rear floor over the pump and did it all from the top. Even doing it from the top, that lock ring was still a PITA.

    I just unbolted the skid plate at the front, and bent it down in the rear so it would clear, no bumper removal.

    I also drilled holes in the middle of the skid plate for drainage...did you notice the tank/skidplate was rusted right in the middle from sitting water/dirt like I did?

    Scooter, where and how much of the floor did you have to cut. I may have to change an in tank pump on my g/f's 88 and am thinking of making an access hole for on trail repairs.

    TIA
