PB Blaster and a blue wrench, if you have the room. Otherwise smack it with a hammer a couple times.

I changed the pump in my 06 2500. I dropped the tank. I used a couple floor jacks and lowered it enough to disconnect the lines and wires. Then dropped it the rest of the way. My sending unit was cracked at the top and was throwing evap codes. Also I replaced the locking ring as it was so rusty it was toast. Not a easy job but not the worst I ever tackled.

thinking about cutting a door in the bed to get to the pump...

There's really no need to do that, Terry. It was tough to get the bolts out of the bed of my 2001 Ram too. But whichever way you decide to go, stick with it and tough it out...you'll get it one.

-Use a brass drift don't go smacking things that can spark By the way just ran into a stupid issue like that on a 2009 Journey it was the battery being below 12 volts Replaced the wheel well battery On a lousy day outside and all bolts were naturally rusted / frozen I have few choice words for the genius who made that design Starter sounded like it wanted to go but could not just whirred

if I had a air impac gun it wouldn't be a problem to lift the bed

Is there enough room for a cheater bar on a 1/2" drive ratchet? What about a small ratchet strap on the end of the ratchet to get 'em broke loose? Let us know what you come up with...

My father had a electric 1/2 dr impac gun i couldn't get them loose.. I spray the bolts with pb blaster.. I'm going to my friend shop this weekend if it don't rain he has air compressor. i got my finger cross if that don't work then we had to drop the tank. i really don't want to do that I'm not sure if he has a transmission jack.. I don't have the money to rent one either..

I'm happy to say I got my truck going again! i want to thank my best friend for helping me!! I don't know what I would done without his help!!
