Gas Tank Sealers

Hey Guys, I am working on a nieghbors Oliver 66 and his gas tank is rusted badly inside...He had it "steam cleaned" last summer by another shop which looks to me might have made it worse. I have often seen but never used the sealer kits like the ones from Eastwood. Anybody have first hand knowledge or tips on these and if they really do work or not ? Thanks ! ~ Mike
 
I have used Red Kote. The main thing about any of these liners is to get the tank clean and dry before putting it on.
 
The car restoration folks, Eastwood, sell an excellent kit that has everything do the job from start to finish. I've used it twice and have been pleased with the results and amazed at the size and amount of pin holes it would fill without running through to the outside. I highly recomend it. When I last used it 6 or 7 years ago it cost about $55 to do a medium sized tractor tank.
 
I had the same problem with my farmall H. It had sat in our un-heated family pole barn, out of the weather, but not out of the humidity here in Indiana. The tank was badly rusted. I had the tank chemically cleaned and then used Redi-Kote. Reasonably priced and was able to get at my local parts store.

Worked great and now the gas in the sediment bowl is as clear and when I put it in the tank.

I have had no problems.
 
O'Reilly Auto Parts stores either stock it or can purchase on line.

Seems to have worked well. Pint can coated Farmall 100 gas tank and my Honda 110 3-wheeler.

I have a couple of tanks I also need to coat. I let one sit for a week with about a half gallon of Acetone in it. I sloshed it around with a peice of chain for about 15 minutes off and on, and also steam cleaned it after pouring out the Acetone. To me it doesn't look any cleaner.

What would you guys recommend doing to clean it/prep it so I can put some Red Kote in it?? It had old gas in it and was gummy and also had some rust. Should I take it to a radiator shop? What will they do to it?

Acetone will only take out the bad, old gas and varnish. It will do NOTHING for rust. You have to use Muratic Acid for the rust. I'll go find my old post on how to clean a tank properly.

Here it is:
(quoted from post at 08:33:17 02/09/11) I just got off the phone with the chemist at Red-Kote. Yes, Northern Fuel Tank Liner and Red-Kote are the same thing. One is dyed red and one is dyed blue, that's it.

- If you think you have varnish or heavy rust use a chain to break it up.
- 1 part Muratic Acid to 3 parts water for 30 min
- Rinse with water 3 times
- Rinse 2 times with Acetone (MEK will work, but acetone is cheaper)
- Dry overnight
- Coat tank per the can

Here's a .pdf file that is more informative than the can.

Thank you for the reply. I did use a chain while the Acetone was in there, but it didn't seem to help much. I've heard of taking them to a radiator shop to get them "fixed". What will they do for the tank? Clean it or both clean and cote it? Thanks.
 
Most shops would do either. Just be sure you are clear with them when you take the tank in. If you were using the tractor for farming everyday you could probably not coat it. But most of us only have 1/4-1/2 tank of fuel and that leaves a lot of potential for rust. If I went to the work of getting one boiled out or I cleaned it myself I would probably go whole hog and coat it as well.
 
So, do you think I should just clean it with muratic acid myself, or let the shop do it? Which would be better. I am sure that the coating part isn't that hard to do. Thanks for all of the help!
 
Do it yourself. The muratic is only like $5/gal. It is pretty easy to do yourself. I would do two coats of the sealer. I did one and it seems thin, but all it takes is a film so it is fine.

Does the sealer stuff have self explanitory directions, or is it a tough task? Should I just put a pipe plug in the bottom of the tank where the sediment bowl goes and pour the sealer in the top & slosh it around?? What is the best procedure? THANKS! So far, it sounds like Im gonna do it myself.

Read the directions in the quote that I did above. Self explanitory. Just make sure you dont' seal up your opening with the sealer. You have to take the pipe plug out when the stuff starts setting up and run your pocket knife around the opening.
