 Topic: WD45 Gas tank leak
Posted: 25 Jul 2011 at 6:57am |
The tank on my WD45 has a pin hole leak on the bottom close to where the sediment bulb attaches. I noticed several other small pits in the area also (not leaking yet). Most of the tank looks pretty good and the inside does not appear to be rusty. I would expect that others restoring these old tractors would have some experience in repairing leaky tanks.
I have found internal tanks solutions that promise to coat and seal the tank from the inside, I found compounds one can apply like epoxy on the exterior, and of course I have the option of welding the hole shut by the local shop.
What have been your results when you used the products to fix the leak?
Thanks for your advice!
Steve

You might look to see if you can find a replacement tank first. It will be a lot easier and less painful than doing a lot of work and not being successful. Several vendors on this site have parts available.

Seal coatings work really good but the inside of the tank has to be really clean for them to hold.
I have brazed many would good results.

After cleaning my tank on my 44C, I had about a dozen pinholes in the bottom of my tank. As I was not able to afford to buy redkote at the time, or at least I had no way to get any in a reasonable amount of time; I stripped the paint on the outside and applied a coat of JB Weld on the outside of the tank, over the holes. I then repainted the tank. That was 3 years ago and I haven't had a leak since.

I use JB weld on the larger holes by first picking the rust from around the hole, then use Red Kote inside.

Seen many just soft soldered with tin/lead solder also and there are other 2 part epoxies also one can use on outside to fill the voids and smooth out tank but the best results will come from sealing the inside also.

Used Jb to welded my Ford about ten years ago. Still working. Have seen them solder a true copper penny over holes as well.

I JB welded quarters over the holes in my tank! They happened to be the right size.

The JB Weld seems to work quite well when the outside surface is nice n' clean. I had a bunch of pin holes in the bottom of my very first Model B tank. After glassbeading the outside, and washing it down with thinner, I skim coated JB Weld over the holes a couple times in between sanding. I then sealed the inside. That was 9 years ago. Its still holding. I now take my tanks to my Radiator man for repair. He does a nice job, and I don't have ta' mess with trying to fix the tanks. He seals the inside also for me... HTH
