My failed search to find a new fuel tank for 1941 Oldsmobile 66 series has left me no choice but to try sealing it. What is a good sealer to use and how much do I use? I think it is about a 15 gallon tank.

I know you have already probably thought of this already but have you expanded your search to include 40 to 48 Chevy Coupes? I think they have the same tank though I could be wrong? If I remember correctly from my 41 Chevy, it's a 15 gallon tank. Depending on where your tank is leaking, it could be paper thin in more than one place. I'm sure the rest of the guys will chime in here and tell you how to seal it, if you have to resort to that.

I know for a fact that POR-15 leaves a film that's tougher than nails.
Kwik Poly has also been highly recommended but I don't have hands on experience with it.

Will, Since it is already August and you live in N.J., why not hold off and visit Hershey in Oct. There are re pop vendors there and MAYBE a better tank for you.

Will, the tank sealer that Langs sells works well, but a new one would be better.
BTW, do they still race at the track in Evans Mills? Is it dirt or asphalt now?....Chip

two years ago, I used the POR 15 Tank seal kit on my '26 cowl tank and it worked and still works like a charm. As Craig said, it's as hard as nails. I simply followed the instructions, sealed the outlet with a pipe plug and the fill opening with the tank cap and poured the entire quart of POR 15 into my tank and sloshed it around until it coated every interior surface top and bottom and on all sides of the baffles, then let it drain out back into the original can then let the tank dry. After draining back into the quart can, I have enough to re-use and do another tank. See: www.por15.com/SPECIAL-Sealer-Prep/Productinfo/S7Q/.

Disclaimer: Since I only use regular, non-ethanol gasoline and have never used E-10 in my Model T, I do not know if ethanol would have an adverse effect on the coating. Jim Patrick

Caswell plating has an excellent product called Phenol Novolac. Far stronger than POR 15.

Will, you may look at Pontiac Torpedo 1941-48 also for a possibly matching tank?
Here's what the wiki community says about GM's first A body:
http://alturl.com/xdwzt
"The earliest GM A-bodied based cars were built primarily by Chevrolet and Pontiac. Oldsmobile also used the A-body for the 1936-39 Oldsmobile Series F and 1940-48 Series 60. All Chevrolets produced during this period, and all 1936-39 Pontiacs, the 1940 Pontiac Deluxe, the 1941 Pontiac Deluxe Torpedo and all Pontiac Torpedos produced from 1942 through 1948 were A-bodies."

Does it have a hydramatic? (A planetary trans makes any car more interesting :-) )

Thanks guys, I'm going to go with the Caswell Plating stuff. Maybe some place later I will run into a new fuel tank for the old car.

I used the caswell stuff and it seems to have
worked very well
