Fuel Tank cleaning Options

[Rusty]

I've got minor surface rust on the interior of my fuel tank. Since I'm pulling the tank out for other maintenance, I might as well handle this too.

Any thoughts on the best way to handle this job? I know there is some controversy about the Eastwood/POR kits.

thanks,
Rusty

Thanks for the advice, Rob.

Chemical burns? Yikes. What would you have chosen instead of duct tape?

Long time ago, I remember someone recommending taking a tank to a radiator shop for boiling. I wonder if that would strip the paint off the exterior? I'd rather not have to paint the outside.

I was wishing for big rubber plugs but there just isn’t anything large enough for the top holes. The chemicals in the POR kit are no mystery. I recall muriatic acid which is common pool store fare. If I did it again, I’d find a rubber chem suit. The biggest risk is to your arms as you have to roll the tank around to distribute the chemicals. Maybe an old welding jacket?

I have to do the 240Z tank and I’ll probably just do the radiator shop method. But that’s
because my uppity gated guarded community doesn’t lend itself to working on cars. People have done that forever with good result. Not much price difference.
