I had to use my generator last night - we lost power. Ran into a situation for the first time - had to refill the tank and the sucker was hot! What I ended up doing was putting a wet towel over the engine until I refilled the tank. Everything is back to normal. I got out the owners manual and read all the safety stuff and there was no mention of filling the tank after the engine was hot. Seems like the gas fumes would ignite. Maybe not. Anyone had experience with this?
