    We've been battling air intrusions on our new skidder that we just put a brand new motor.when you shut it off it pushes fuel back to the tank.not your Normal air intrusion.its the sleeve metering fuel system.we can't figure it out at all unless there's something in the fuel filter houseing to stop it from pushing fuel back
    Anyone ever run into this problem or have any advice we're lost on it
