FUEL SUPPLY PUMP REMOVAL

PROCEDURE


  1. PRECAUTION

    Note


    • After the engine has stopped, wait at least 1 minute before releasing the high pressure lines.

    • When working on the fuel circuit, protect the generator assembly against contamination. Cover the generator assembly with suitable materials. Failure to comply with this procedure may result in a generator assembly malfunction.
