The Stovebolt Site Forums The Parking Lot Tons 'o Fun Cleaning and sealing the gas tank

When I removed the gas tank and drained it I found lots of crud rolling around in it. What would be best to use to clean it and is there something that should be used to seal it after?

Hey New Guy;
Odds are if you got alot of crud out of there it needs a good cleaning. If you have a local Radiator repair shop they can usually drop it in a tank of cleaner that will clean it and get rid of the rust (and check it for leaks as well).

Once thats done there are alot of good tank liners out there, Eastwood, POR, etc... Odds are that your local auto parts store has a good lining material that you can pour in and swish around.

I've also heard that KBS makes a good kit that includes a cleaner, de-rusting agent, and a sealer. Depends upon how much you want to do yourself. Googling, I found this with a video of the process http://www.kbs-coatings.com/auto-fuel-tank-sealer-kit.html

Personally I like Kano's EXRust for neutralizing the rust, but thats just me. Good luck - here's hoping there are no leaks!

Thanks WishekBruce

I will check that out. I believe the tank is good as it had 1/2 tank of fuel when i got it. I had a hard time draining it as the line out the bottom kept getting fowled with sludge. I would just send a little air up the tube and it would drain again. I have heard horror stories from some of my motorcycle friends that have had older tanks re-lined and loosing gas flow due to some of the liner coming loose and fowling the petcock up.
i'll check out the video and rad shop...never would have thought to ask them.

Thanks Again

I have always had good results using the POR 15 Kit
