I would say most any rubber washer of similar size and thickness will doo the trick. Some rubbers don't react well with fuel products though... nothing that will deteriorate over night, but may over time. should be a good quick fix so you can ride until you get the correct one. I'd definitly find another dealer as well... nothing worse than buying a big ticket item then they dont want to help yopu maintain it! The dealer i bought my 4 wheeler from told me they couldnt mount the tires for my 350 X because it was motercycle season....I'd have to wait 3 weeks!!!!!!!!!!!!!!! Yeah.... never going back there again!
Good luck with the washer, the plumbing section / faucets will have the best selection of rubber washers. Hey, cant be worse than the one that was on there right!?!?!?
