I have a used 280SL fuel tank for sale. I cleaned rust out of it about 12 years ago and used it, but the car sat since then and the gas went stale. I just replaced it with a new tank that I had long ago purchased for this car, so this older one is available. It doesn't leak, but it's not new either. $100 plus shipping, but I would greatly prefer some sort of pick up or handoff in the greater New England area.
