J-B Weld 2110 Metal Fuel Tank Repair Kit Gray

Driving down the interstate and ran over a tow strap where the metal hook bounced up and put a hole in the oil pan. The stealership quoted $1,400 to replace the pan parts and labor. Ordered this J-B Weld Fuel Tank Repair Kit thinking what the heck it's worth a try. I didn't know if it would work on the oil pan made of aluminum but it did! It stoped up the hole just great! No more oil leak and instead of fourteen hundred bucks to replace a pan, the hole was repaired for fifteen. The kit comes with a small block of wax to put into the hole just to stop the leak while you prep the area around it. There's some sand paper to rough up the area around the hole to help the epoxy have something to grab. Mix a bit of the resin and hardener together using the supplied brush. Then, goop that first mixed batch over and around the hole and put some of the supplied fiberglass patch ontop of that first layer. Next, mix the rest of the packets of resin and hardener together and brush / goop it onto and past the edges of the fiberglass patch. It dried within half an hour and I was driving the car within an hour. Bumper to bumper traffic stop and go for several hours later and back home then let the car sit for a few more hours and crawled underneath and looked closely at the repaired area feeling all around for any signs of oil. Dry as can be and absolutely no more oil leak. Seriously, thanks for a fine product that saved me time and real money. Read more

It worked well on a 56 Buick Fuel tank, sealed it up right away! Read more

Used it to stop a leak on an oil tank from a pin hole. Worked well and hasn’t leaked since. Did the repair about 6 months ago and still holding. Seems solid Read more

This product may work on Metal gas tanks but it does not work on HDPE gas tanks. Label states it works on plastic containers and doesn't specify HDPE gas tanks. Don't believe the youtube videos on this product for car HDPE can tanks, it will only last a few weeks. Read more

This seems to be a very tough tank weld and it fixed the leak that I had (which I will describe further on), BUT, the most important takeaway from my review is DO NOT FOLLOW THE INSTRUCTIONS!!! Because if you do, you will end up with an unbearably hot, rock hard bag of glue! The glue will start curing by the time you finish mixing it in the bag! It is EXTREMELY important to first empty the black compound, and then empty the white compound beside it. I would recommend doing this on a party paper plate. And when everything is ready, start mixing the two compounds together with an 1 inch wide wood shim. If you do it my way the glue will cure in approx 8-10 min from the time you start mixing, vs approx 3 min from the time you start mixing if you mix it in the bag like the directions tell you. I know because I tried it both ways. I used it to fix a large rusted and pitted area or a John Deere 2640 gas tank, and the fix seems to be incredibly sturdy! I hope this helps somebody!

I've used this on two gas tanks that have had small pin holes that leaked. Both tanks have successfully been sealed without failure. Read more

Mixed feelings about this one. I’ve used JB Weld for years, but, only tried to apply it where I thought the product would function best. I had a crack in a fuel tank. I was able to clean everything off of it, while in the car, and with the help of a electric solder iron did the repair. It was difficult to get it 100%, still a slight bit of sweating. When the tank was completely dry and completely clean, I applied the JB will patch kit. it was a difficult process!! Laying on my back, applying this upwards, trying to get the cloth and the Epoxy in the right position. I wasn’t really happy with the job. However, the leak went away. For about four months the Repair seem to be good. As I feared, the leak came back. I removed the old JB Weld, which didn’t seem to have very much adhesion , it came off in one big clump. Re-solder the area, this time with the gas tank cap off so there was no pressure, and reapplied a new JB Weld tank repair kit. This time, I did not use their nylon material, I used metal screening, and, I mix the epoxy in four different batches, it is much easier to work with and you’re able to layer it in a much more efficient manner. As of now, as before, the patch is holding. We’ll just have to see where it goes in the future. I’ll continue to use JB Weld products, as always, the preparation of the site, and how it’s applied is pivotal whether or not this cold patch works effectively. If the leak continues to return, I’ll post that in the future. *** UPDATE*** 06/24/25 It failed again!! Same as described above!! Damn!! Lasted about 2-3 weeks then a very small drip. Parked the Geo. I tore it down and exactly as before. No adhesion!! The patch just popped off with a screw driver. So, I’m done with quick fixes I Ordered a Dorman tank replacement and will r/r it when it gets here. Very disappointed!! Again. I’ve used JB weld with better results. Not this time X2!! Read more
