  2. BEFORE WORKING ON FUEL SYSTEM


    1. Do not work near an open flame.

    2. Keep gasoline away from rubber and leather parts.

    3. Discharge the fuel pressure before disconnecting the fuel line to prevent gasoline from spilling out. Refer to the following procedure.

  3. DISCHARGE FUEL SYSTEM PRESSURE

    CAUTION:


    • The Discharge Fuel System Pressure procedures must be performed before disconnecting any part of the fuel system.

    • After performing the Discharge Fuel System Pressure procedures, pressure will remain in the fuel line. When disconnecting the fuel line, place a cloth or equivalent over fittings to reduce the risk of fuel spray.
