Thanks for the good info Railbird,,,,,I replaced my pump last year just for the piece of mind..it acted up on me 2 years ago,it left me stranded for about an hour far from home..it seemed to straighten out on it's own and got me home...I wish Yamaha would just come out with a recall..I read somewhere on here that there is a recall in Japan but not here....well I figured out with your help that my new pump was built December 06,2010.so I should be good,,,,thanks..Jason
