I am cleaning up a power unit, to operate my corn grinder. The fuel tank was rusty, I sandblasted the interior, with a hand held blaster. Was able to fit a shop vac hose inside, to clean out the grit and loosened rust. (No baffles, in the PU tank.) Acid bath, followed by Redkote, and it will be ready for another 60 years of service. Ed
