is JB weld gasoline proof??

There is a product called Sealall, it is gasoiline proof, for a long time. We used it to repair gas tanks until they could be properly soldered later. Sometimes over a year later.

Before Reher & Morrison started selling the epoxy I use now, I used to use nothing BUT JB Weld to reshape intake ports on drag & road race engine cylinder heads. I NEVER had any of it come loose. It was in gas the entire time the engine was running ALONG with heat cycles & expansion & contraction. Granted, it was vaporized gas, but gas still the same. Ray.

sending unit is all repaired and back in the gast tank. Of course then the fuel pump would not work, but I expect no less after two more gas tank/sending unit removals everthing works now . thanks for all the help

Count me in as someone who repaired a broken carb float post with JB Weld. Held up for as long as I had the carbs, which was a long time. I also used JB Weld to repair a stator cover that dragged on the ground for a while and had a 1/2" hole in it. That wasn't gas, but it's hot oil being washed through there, and that cover was leak free for tens of thousands of miles.

There is a similar material called Water Weld that is for sealing gas tanks.

The ticket is make sure it is JB Weld and not JB Kwik, the faster drying product.
