Rebuilding fuel pumps

[TrueBlue]

Does yamaha sell rebuilding kits for their fuel pumps. Not sure if that is the problem I am having but need to consider doing this. I am also putting in 2 new check valves by the oil pump. The reason that I am changing the 2 vales & rebuilding the fuel pump is because my oil container is filling up with gas.
None of the gas/oil lines have been disconnected or moved. I did find a pinched gas vent line from the top of the gas tank but I am not sure if that is going to take care of the gas going into the oil container.

Any help would be appreciated.

there is no rebuild kit for the fuel pump.only options are a new or used one.the check valves are most likely the cause of the gas in the oil bottle.

The valves do not normally wear out. Take it apart and see if there is something keeping the valve from seating. You should be able to get parts at a Cat dealer or possibly Ski-Doo or Polaris, or an aftermarket supplier.
