Sight Tube Inspection
1
The engine is equipped with fuel system sight tubes which provide a visual indication of a problem in the fuel
delivery system. There is one coming from the mechanical fuel pump and one coming from the vapor seperator
tank. Both of the tubes are joined together and drain into the intake manifold. If there is fuel visible in the sight tube,
have your engine repaired by an Authorized MerCruiser Dealer immediately.
