Fuel Tank Restoration

***TitaniumTT*** · 01-02-2011, 10:46 PM

Unless it specifically says compatible with high content ethanol fuels, I would stay FAR FAR away from it.

I had what I'm sure is a similarily nasty tank, took it to a radiator shop. They boiled it, pressure washed it and sealed it. Worked great until a few year ago when the sealer started failing and it clogged more than a few fuel filters.

I would go so far as to boil it, maybe get some heavy duty acidic cleaners in there but I wouldn't use any sealer at all.

FWIW, if you're premixing, the premix does an AWESOME job of staving off rust and corrosion inside the tank

One of my friends used the POR15 stuff to restore the fuel tank on his mid-'60s vintage box Nova a few years back. He hasn't had any problems with it since, but as I recall this restoration process is very sensitive to following the directions to the letter - especially WRT getting the tank clean & completely dry before the sealer gets applied.

Don't know about POR15's ethanol compatibility, but the pump gas around here that he's been running on uses it, however the max. ethanol content is <= 15%. He hasn't run it on E85 or anything with a high ethanol content as far as I know.

I'll check with POR15 and see what they say. Thanks for the input.

I do premix and hopefully it's helped, but the tank is pretty crusty. I couldn't get a pic of the tank but here's the fuel pump sock. Keep in mind I cleaned this about a week ago and drove it ONCE for about 5 miles.
