      Disengage the claw and remove the No. 1 fuel pipe clamp.

   2. Disconnect the fuel tube sub-assembly from the fuel pipe.

      
      
      1. 

         *a	Retainer
         *b	O-ring
         *c	Fuel Tube Connector
         *d	Fuel Pipe
         *e	Nylon Tube
         	Pinch
         	Pull

         Pinch the retainer of the fuel tube connector, and then pull the fuel tube connector off of the fuel pipe.

         Note

         Be sure to disconnect the fuel tube connector by hand.

      2. If the fuel tube connector and fuel pipe are stuck, push and pull the fuel tube connector to release it. Pull the fuel tube connector off of the fuel pipe carefully.

         Note

         
         

         • Be sure to disconnect the fuel tube connector by hand.

         • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the fuel pipe.

         • Do not forcibly bend, twist or turn the nylon tube.

      3. Check if there is any foreign matter on the sealing surfaces of the disconnected fuel lines. Clean them if necessary.

      4. Cover the disconnected fuel pipe and fuel tube connector with plastic bags to prevent damage and contamination.
