Fitment Notice
Match part 104884-59170 and the diagram item to the engine’s serial-specific fuel pipe or fuel oil system drawing. Nearby gasket 23414-080000 is a separate 8 × 1.0 gasket and is not interchangeable based only on nominal opening size.
When to Replace
Install a new washer when the fuel-pipe joint is opened, or replace it if the existing washer is distorted or fuel seepage appears at the connection.
Installation Notes
Clean the mating faces and tighten the joint according to the procedure for the specific engine. Avoid adding sealant to the fuel connection unless the service manual directs it. See the Yanmar 1GM10 Fuel Pipe diagram, Figure 42.

Can 23414-080000 be substituted? No. It has a different part number and should only be used where the engine diagram specifies it.
