CANISTER INSPECTION

PROCEDURE

1. CHECK CANISTER (FUEL SUCTION PLATE SUB-ASSEMBLY)

   1. Visually check the canister (fuel suction plate sub-assembly).

      1. Visually check the canister (fuel suction plate sub-assembly) for cracks or damage.

         If cracks or damage are found, replace the canister (fuel suction plate sub-assembly).

   2. Inspect the airflow of the canister (fuel suction plate sub-assembly).

      1. 

         *a	Port (A)
         *b	Port (B)
         *c	Port (C)
         *d	Air

         Close the port (B) and check that air flows from the port (A) when air is blown into the port (C).

         OK

         Air flows from the port (C).

   3. Inspect the check valve.

      1. 

         *a	Port (A)
         *b	Port (B)
         *c	Port (C)
         *d	Air

         Close the port (C) and check that air flows from the port (B) when air is blown into the port (A).

         OK

         Air flows from the port (B).

      2. 

         *a	Port (A)
         *b	Port (B)
         *c	Port (C)
         *d	Vacuum Pump

         Using a vacuum pump, apply vacuum to the port (A) with the port (C) closed and check that air flows into the port (B).

         OK

         The vacuum is maintained at first. By gradually increasing the vacuum, air flows and the vacuum decreases after the vacuum reaches the a certain.
