I just changed mine out do to leaks in off position. Not sure of the P/N coming out, but it didn't have any of the balls to open and close ports. The "direct" replacement part was far from it. The shaft looking up is a "D" shape. Had to adjust the look just a bit with a file. Also the mounting holes don't line up, and the fuel line came up short.
All done now and it sure feels great.
