Deformed gas tank - why?

I just stared rebuilding my CJ7 (my major mile-stone so far is that I took the body off the frame). I dropped the gas tank, which is stock, and it looked very deformed. Attached picture does not do it justice - there are hills and valleys all over the tank surface. My question is why did this happened? My best guess is due to heat (used to live in AZ) and pressure. What do you think?
What would be a good, safe, reliable replacement tank - fuel cell or just to get another OEM tank?

Re: Deformed gas tank - why?

1. I agree it's due to the heat in AZ, coupled with
2. a possible clogged vent problem
3. Causes the tank to suck in,
4. And the plastic deformation to "set" with the heat.
5. Check those vents!

I agree witth LEVE, clogged vents causing a vacuum to form in the tank, sucking it in. Happens occasionally in refinery's etc when a vacuum breaker fails closed on a big storage tank and the pump is still sucking away.

Re: Deformed gas tank - why?

Yea I would say the same when those vent's get bunged up the tank can do some crazy things. After a day of wheeling mine was clogged with mud and the tank sucked itself in so far that the fuel sender was bent and lifted up outa the gas which equals a tow home but all in all it was fun!1
