I don't want to get a reputation as peddling stuff I find on eBay, but I honestly stumbled across these when I was searching for a piece of info on google. I know I'm not the only one with one of these motors out there. I'm thinking about buying another pump as a spare, especially if I ever do a WVO conversion.
Seems like a good deal, even just for parts...
