SPRING LOCK FUEL LINE COUPLING MAY NOT BE PROPERLY ENGAGED.
Consequence & remedy
Consequence: COUPLING COULD DISENGAGE DUE TO FUEL PRESSURE,VIBRATION, AND ENGINE MOVEMENTS; THIS WOULD CAUSE LOSS OF FUEL WHICH, INPRESENCE OF AN IGNITION SOURCE, CREATES A FIRE RISK.
Remedy: INSTALL RETAINER CLIPS OVER THE COUPLINGS TO PREVENT COUPLING SEPARATION AND FUEL LEAKAGE.
