Extra Gas Tank Removal, '72 GMC
My pickup has 2 extra tanks and I need to remove them both to do some cleanup work. They may go back on they may not, the in cab tank is in good shape and this is not my daily.
So, my question is what tool is required to get these things out? From the underside of the cans, it looks as tough there is a spot for a 3/8" drive with 2 small holes on either side. I tried to just place a 3/* drive in there but it's too small and will strip the female if I give it the beans with a breaker bar. Can anyone put me onto the correct tool here? Super green here with these specific vehicles........little help please?:gmc2: |

Not sure if you can see in there with a flash light. Mine where easy to remove. I think I used a deep 9/16s with a 12 inch extension. I sprayed them with penetrate for about a week before trying.

I had to cut the bolts out with a grinding wheel from the top of the bed. It was a pretty simple deal but be careful those tanks are pretty heavy. My tanks were completely rotted on the inside and full of rust and corrosion, so no way to reuse them anyway. Now getting ready to remove the riveted doors on the side of the bed and put a patch panel in.

They are just carriage bolts on top to long nuts on the bottom. I'm pretty sure I just used an impact and 3/8 or 1/2 inch extension. I broke on and have only replaced itr with all thread and ny-locs. Mine were in pretty good shape so I just cleaned and flex sealed them.

When I had the tank on the shop floor, the bolts were rusted in the holes through the tank. I used a BFH to drive the bolts out. The tanks are plate steel so they do take some abuse. When I had the bolts out I cleaned those holes out with various tools to remove the Wyoming clay and rust. The tank I sent to a shop to be cleaned as it had a leak in a corner. They said because of the plate steel they were able to fix the tank for use. They stated that a stamped sheet metal tank that old with that type of leak would have been a goner. When I got it back I made long carriage bolts out of short, 1/2" carriage bolts and 1/2" all thread. The re-habbed tank has been hanging there for at least 10 years and is used every time I fill the truck. |

Ok, so I'm not crazy and have been hunting a unicorn tool from a fantasy land! Sounds like my HF angle grinder is about to earn it's keep!
Case closed, over and out! |

Can anyone tell me how to remove the behind the seat tank of my 1972 Chevy C10? Additionally, how do I move the seat back forward, there is no lever.

Now you can get to the tank itself. Mostly, it's bolted to the cab floor. Remove these bolts, and it should come free. Pull from the passenger side up and away, while your buddy shoves the filler neck down thru the grommet. With the seat out, you can work on your slide mechanism. |
