Right on. I hope it lasts. Keep us posted.

The U.K. large Standard tank, very tempting...

That's a 6 gallon tank? Nice, but mine has no visible rust inside. That color might work with mine. And it comes with the rubber grommet.

Would that tank need to be cleaned with chemicals and shaking it with bolts to get the rust out?

It's 6.3 gallon, the inside looks pretty clean, the picture of the inside shows shiny metal, maybe a tiny amount of flash rusting which wouldn't be a deal breaker. I would run it with a fuel filter anyway which would catch anything. It's pretty normal for some flash rusting to occur with it sitting dry.
