   CAUTION:

   Before separating a Quick-Connect fitting, pay attention to what type of fitting is being used. Refer to STANDARD PROCEDURE - QUICK-CONNECT FITTINGS . This will prevent unnecessary fitting or fitting latch breakage.

   NOTE:

   Excessive fuel spillage onto the gaskets can cause gaskets to expand and dislodge from gasket groove.
