I did it. I just ordered one off of e-bay at discount cycle parts. Found it for $30.00 and that's shipped. Sears wanted about $80.00 which is just plain nuts.
A lot of local guys are packing one of these in their bag now, it's like putting on a rain suite and it won't rain, carry one of these in you saddlebag and you'll never run out of gas LOL, well at lease you don't have far to go to get gas. I think I read they even sell them at Sears now.
