Andrew - I use Bilt-hammer Deox-C to derust my tank internals. You Do need to flush out any gunk/varnish residue first. I normally remove the stale fuel, then degrease / flush (if you’re careful you can use a pressure washer lance to clean out internally. Then make up a Deox-c solution with hot water and fill the tank with the solution warm.Sent from my iPhone using Tapatalk Pro
