Leaking Gas Tank - Fix or Replace?

So I finally had the time to pull my tank off and I found what appears to be the culprit of my gas leak. Looks like it's leaking from the seam.
Does anyone know a good way to fix this or am I looking at having to replace the tank?
Also...what the heck is that red crap??

Thanks y'all!

I don't know what the red crap is but if that's the outside of the tank what the hell does the inside look like?

I think you will be needing a replacement tank but you may also be able to do a short term repair with some JB Weld or whatever.

The red crap is to stop rust I would think.

There are putties on the market that will seal a hole and last a lifetime but a seam can be a hole other problem, the leak can just keep growing over time or it may never grow at all.


Sealing the tank from the inside is a proven fix if you follow the instruction to the letter.


Now the decision is do you have the time, the place and the skills required to seal the tank.

Then you would need to look at the cost, tank sealer and your time verse a replacement tank.

Lets face it that tank has seen better days.....

I think I'd start out with the cheapest solution: a Tank Weld kit from JB Weld. It's about 12 bucks from Amazon. It's basically just SteelStik two part epoxy putty plus some fiberglass mesh for added strength. If it's leaking along a weld seam, the mesh should help seal it better.

Thanks y'all for the suggestions. I'm going to get that tank weld to get the leak fixed for now and start looking for a replacement tank. As @Rolex said...that tank has seen better days. lol

I have had great success with pin hole leaks or small leaks at seams using KBS

Look up kbs-coatings Dot com

Its not the cheapest solution and it is somewhat time and labor intensive but you should never have to think about the tank again. I dont know what a new tank cost but the coating should certainly be cheaper than a new tank .. I am guessing

I would look at the inside of the tank also. The tank could be passing debris into the fuel system and take out a lot of expensive parts in the process.

I'd toss that tank in the bin and buy a good used one. There are lots of choices in the $150 to $250 range on the big auction site.
