Mothballing curiosity question

[Dieselmeister]

Of the eight generators I have bought over the years, all of them (from the little 531 up tp the 802) had absolutely clean fuel tanks, with no diesel fuel residue or smell. I am just curious, do they remove these tanks, and wash them out before they go into storage?

No. Not even. Drain them, yes. I have picked up gen sets from long storage, POMCUS, for instance. Set was clean and looked OK. But the tanks are not drained, and washed out.

I got one once with an unknown substance in the fuel tank. It was yellowish and when soaked into a white rag, it was like cracking a highlighter open. I am fairly sure it could have been seen from orbit. This is the same set that was full of kittylitter. Turns out the oil drain valve was a bit leaky.

Then theres the ones that you could eat off of.
