Default Gas tank sealer suggestions?

Hello All,

I have a Delco-Light Model B-12 generator with a small sheet metal tank that leaks very slightly (pinholes, I think). The tank is very slightly rusted inside and it has baffles.

What's a good product for sealing it?

Thanks,

Warren

I have used KBS on several different tanks. Tractors and small engines. I have had very good luck with it. Good luck!

I am really happy with the results I get from Red-Kote brand sealer, and it is available from O'Reilly auto parts for about $23 a quart.

I've had good results with Bill Hirsch Gas Tank Sealer < http://www.hirschauto.com/ >. I've used it in chainsaws & small engine gas tanks and the guy who turned me on to it used it for automotive gas tanks.

For large holes, a little JB Weld on the outside to cover the hole (let it harden) and then gas tank sealer inside.

A motorcycle collector friend used to swear by a product / sealer named KREEM, not sure if it's still available.

I use and like "U.S. Tank" from the POR-15 guys. It looks like a galvanized surface when cured and works with todays ethanol fuels.

Have used Red Kote many times on old car resto's and old engine tanks. It is very good.

Hi, tried them all but there is only one reliable way to seal pinholes in the bottom of a fuel tank and that is to solder a blob over the hole. I use a 75 watt electric iron and normal multicore solder, the steel takes the solder very well and its very quick and easy to do and its permanent. Hope this helps.

I bought sealer from Lee Pedersen (sponsor here) and had very good luck with it, it seems to resist the ethanol fuels better than some that I tried in the past. That said, I didn't use it to fill holes, just seal seams & keep the gas/ethanol from attacking the JB Weld that I filled the holes with.

" KREEM " is still around. Many antique motorcycle restorers use it. Follow directions exactly !

If you have a leak on your tank and you need a emergency fix I know what to do.
Rub a bar of soap on the leak.
I learned that from Gus Wilson and the Model Garage. Who remembers his young helper Stan Hicks and what about that cheapskate Silas Barnstable. [Popular Science magazine car mechanic]

Jeffk,

Thanks, that reminds me of being shown, about 40 years ago, that Oxydol soap would seal a leak. I didn't know other soaps would work.
I'll certainly keep it in mind. As a matter of fact, I could have tried it this morning!

Thanks again,

Warren

Watch what you use, not all sealers are good to go with Ethanol. I use red-kote and I know it works with that.

I'd reccomend you patronize a sponsor of this site,because without our sponsors we just might not have SmokStak. Like Zira, I've had excellent results with Lee Pederson's product and I won't hesitate to reccomend it.

I've found that if the pin holes are small (they really are pinholes), you can wrap some masking tape around the tank, and then treat it with tank sealant and the holes will seal; you may need to do it several times and give the sealant a few days to dry.

Thanks Craig,

Mailed my order to Lee Pedersen yesterday. I'll wrap with masking tape as you suggested.

I don't recommend JB Weld for tank or any fuel system related repairs. I used to think it would work on anything and have used the product for many years however, I tried to use it to repair a cracked/broke off carb flange and venturi on a M-S vh model carb. I made several attempts even after letting the epoxy cure for several days before installation the oxygenated fuel we have in CA attacked the repair eventually dissolving from the fuel while I was test running an engine. A lesson learned from the benefit of others failures ....
