What is leaking

37chief · May 28, 2015

I stopped to changed a couple blades on my flail mower. I ran over the only big rock in the 4 acre field. I even knew it was there. So while stopped I see something leaking. To my surprise it was diesel fuel. The tank developed a one inch long crack about 1/3 from the bottom. There I stand seeing fuel leaking out of my tractor. What a helpless feeling. I am about 15 miles from home. All I did is take a stick and wedge a paper into the leak. It still leaked, but I got my tractor loaded and headed home. I had a bucket I put under the leak on the way home. I would probably be in jail by now if I was stopped. I am goung to use JB weld on the leak. I have had good success with it. Stan

I am waiting on some JB weld on a radiator I have been trying to fix. Top seam of it leaks and as long as it is I figured to solder it up would get it to hot and the core might start leaking so doing JB weld instead

Stan, go to NAPA. They sell an epoxy special for gas tanks. Ask if it will work on diesel. I've used JB on a gas tank and it didn't hold up long.

Old Chinese secret say bubbly gum an duck tape have 1001 uses. OR, jest don't put over a third of a tank of fuel in it........

I've been having the same problem with the poly tank of the sprayer all day. Five loads sprayed out and five times I'd plastic welded it.
I thought I had it fixed day before yesterday before I even started,but every load there's been a leak somewhere else in the original crack. I just did it one more time and that's the last chance. I've only got one more load to go after supper then I'm done.
I finally wised up and realized that none of the three kinds of rod that came with the plastic welder was right for that kind of plastic so I melted it all out and scraped it out with a screwdriver. I went and cut some narrow strips around the fill hole on another cracked tank and I've been using that for rod. It just keeps popping up with tiny little holes. I hope the sixth time is the charm.

They do have it I believe for diesel-better than jb weld IMO.Mark

I have had good results using fiber glass epoxy, with the cloth. You know, A kit meant to repair a car body... A couple layers of cloth is needed to cover the crack and keep it from spreading.

On this radiator there is a seam leak so have a 1/8-1/4 inch wide gap O can fill with the JB weld and have done so. I rigged up a way to hook a garden hose to it to find where it leaked from

Yep,

Patch it over here and tomorrow it'll be leaking over there. I'd sure be looking for another tank.

I have used gas tank sealer only once so I'll call myself a one time expert on the subject. LOL I got the stuff you knead and roll between your hands and it was so dry and crumbly it didn't stick to anything. Out of desperation i mixed a little gasoline in it to dampen it and after that it worked like a champ. This Happened all of ten years ago and it is still holding.

I have used J-B weld gray stick on dripping Diesel and it help for three years before the tank was replaced. I now have some J-B weld HighHeat stick looks the same but have not used it yet.

Allan, I sure hope you're wrong. Might be a good idea to scout around to find out what is out there thouth. Stan

Go for it, you can't tell til you try. I "repaired" a water leak on a water jacket cover plate with sprayed-on red Rustoleum spray paint, still holds after about 3 - 4 years.

Old do you have to wait for it to set up a little or is it a thicker mix?

tractorguy2 · May 28, 2015

I have had good luck with jb waterweld. It is a putty and will not drip off.

Bhunt · May 28, 2015

I never heard of that Ill have to try it.

J B weld can take up to 6-8 hours to harden. But in many things it works well. Shoot i have picked up fence row tractor with cracked blocks that had J. B. weld in the cracks. Those tractor became parts machine fast since I will not pass that off on others

37chief · May 29, 2015

I found some JB weld that sets up in about 5 minutes, and dries in 4 hrs. Stan

I have to say I am not much on bubble gum fixes. We patched a radiator on our AC 7010 5-6 years ago. It had a small rub hole in the top of the tank. That JB weld patch is still there and holding tight.
