J-B Weld 8217 TankWeld Gas Tank Repair - 1 oz.,Dark Grey

Drove over a large rock, and punctured a small hole in my 50 gal RV fuel tank. Was planning to have the tank removed, repaired, and replaced at a cost of $700, but decided to use this epoxy to patch and seal the leak. So far its working as advertised. Simple to apply - epoxy is holding with no apparent moisture or leaking. Very cost effective repair.

Works great. Much easier than welding. Fixed a leak on the seam of my steel slip tank.

Used it to plug a chainsaw oil tank and worked great

Repaired a gas tank on my lawn tractor. Seems to hold, keeping the gas from leaking out. Will update as the summer progresses.

I have a well pressure tank that is getting pinholes at the top rim. I ground down the paint, drilled out the pinhole, cleaned the area with alcohol and put J-B Weld 8277 WaterWeld Epoxy Putty Stick in the hole and around the hole. I let it cure for about 12 hours. I turned the water back on and there was a pinhole leak right through the putty. So I ground all of that off, cleaned with alcohol and used this J-B Weld 8217 TankWeld Gas Tank Repair. I let it cure for about 24 hours. So far it's holding; no leaks. This stuff is better because the two parts are different in color so you can see when it's mixed thoroughly where the two parts of the Waterweld putty are near the same color so it's harder to see when it is thoroughly mixed.

Purchased to eek another year out of a gas tank. Worked perfectly and holding up after 3 months of moderate use.

Great repair product

It’s kind of hard to deal with and I ended up just replacing the fuel pump anyway

Best on the market.🤘

repaired a leaking outlet in a plastic gen set tank

Had a hole in my Tomos A35 fuel tank. Size of the hole was around 3mm. After letting it cure for 2 hours and adding fuel to tank, it is not leaking anymore. Update after 2 months: Still holding strong with no leaks
