Fuel Tank: Inspection

Use the following procedure to check for fuel leaks after installation.

  1. Turn the ignition switch "ON" (without starting the engine). Then check the connections for fuel leaks by applying fuel pressure to the fuel piping.
  2. Start engine, raise idle and verify there are no leaks at the fuel system connections.
