removal of gas tank
Posted by: Fubar ()
Date: February 27, 2018 03:28PM

Guys,
I'm going to attempt to remove my gas tank from my 64 monza I bought at Mecum Fla. and have it cleaned and sealed. Are their any past posts or hints anyone can point me to. I'll also be sending out the carbs to be rebuilt, I took the carb filters out and they were full of crap & exhaust smelled like varnish.

Be cautious of sealing material. Many fail and clog the system.

If it is not rusty inside, just flush with clean gas, or drain what you can, and then fill with fresh and add some carb cleaner Marvel Mystery Oil, Sea foam etc.

Removing it is the best but it is a chore.

You can pull the sender out and look inside without dropping the tank. I would do that first. Someone on here said acetone (I think) works great for cleaning varnish. Do a search before you try it. I have never used it myself. If the tank is in bad shape just buy a new one. Clark's has them fairly cheap and they also have stainless senders.

I used POR-15 Gas Tank/Sealer kit on my 63. Turn out great just follow the directions and where gloves and old clothes the sealer will not come off on you very easy and forget about it coming out of clothes. FYI, it is a 2 to 3 day process.

If I may suggest have the gas tank cleaned at your favorite local radiator shop.
Then you will know if it needs to be sealed or replaced. When the tank is re-installed make sure there is some rubber strips or something between the top of the gas tank and the body. I think the 1960 gas tank is a little different from the 1964. Think about replacing the chassis fuel line too.

It worked for me.

I did that on my 65 Corsa. Removed the tank, found the pin-hole leak, cleaned the tank as per instructions, applied tank sealer as per instructions, let it set to cure, installed the tank back in the car. After all that, I would have been better off to replace the tank. Cost difference is minor. And, it is still an old tank. Not worth fixing IMHO.

My 1960 gas tank did not need sealing or replacing after cleaning at the radiator shop. Just to make it clear. And that was in 1988.
Engine and carbs rebuilt in 2008 and still going.

Most radiator shops will not clean gas tanks any more due to EPA regulations.

Thanks for the insight. Really got me thinking. I have a friend who has a video camera with a 3ft cable I'm going to look down via the filler tube first. Then IF I have to I'll take the sending unit off. Try to get this done tomorrow.

Raise front of car at least 30 inches from bottom Suspension crossmember to ground... or use a lift!

On LM's you just rotate the swaybar to get enough room..

Removal is self explanatory... drain fuel, disconnect 2 electrical wires and remove nuts from 2 straps..

If it doesn't fall out

Up top.. 2x2" wood... on top of filler neck... Whack with 5 lb sledge...this will push it thru the old hardened Grommet...

If grommet is still decent.... coat with Silicone to ease the re-insertion of the filler neck...it pushes thru the bottom much easier!

Yes that has been true for decades. The cleaner the shops use is expensive to dispose of so they don't clean things that foul the cleaner quickly. The other issue is most cars now have throw away radiator cores. Cheaper to replace than try to fix.

Considering the effort to pull, clean, and seal an old tank it's easier to just install a new one.

DON'T USE ACETONE to clean the inside of a gas tank - the fumes are explosive!!! It's fine for cleaning with small amounts in a ventilated area.

I have seen a lot of old original tanks. I have seen very few that were truly worthy of not simply replacing.

Check the filler and vent hoses on top. They are often rotten leading to half your gas on the ground at the gas station. This may help in your decision on whether to remove the tank or not.

You can check sender and gas gauge operation with the sender removed and the 2 wires hooked up. You might want to remove it just to have a look at the float and filter. I'm of the opinion that a working original sender is better than new Chinese replacement which is a crying shame.
