Installation Notes

  1. Turn off the engine, allow it to cool, and work in a well-ventilated area away from ignition sources.
  2. Confirm the existing filter and its connections match the replacement before beginning installation.
  3. Relieve fuel-system pressure and use appropriate precautions to contain spilled fuel.
  4. Remove the existing filter according to the engine service manual. Note the fuel-flow direction before removal if an arrow or orientation mark is present.
  5. Install the replacement filter in the same orientation and reconnect the fuel lines securely.
  6. Prime the fuel system as specified by the engine manufacturer and inspect all connections for leaks before operating the outboard.
