Replacement of fuel pump with seal sub-assembly (for high pressure side) Inspection After Repair

  • Poor idle, etc.

  • Engine start function, etc.

CAUTION:


  • B000XRQ

    Never perform work on fuel system components near any possible ignition sources.

  • Vaporized fuel could ignite, resulting in a serious accident.


  • B000XKC

    Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.

  • Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

  4. DISCONNECT FUEL TUBE SUB-ASSEMBLY

    Note

    Remove any dirt or foreign matter on the fuel tube connector and fuel pipe before performing this work.


    1. Disconnect the fuel tube sub-assembly from the No. 1 fuel pipe sub-assembly.


      1. B000XAHC01
        *a Fuel Tube Connector Cover
        B000XM7 Pull off

        Pull off the fuel tube connector cover.

      2. B000YTTC01
        *a Retainer
        *b Fuel Tube Connector
        *c Nylon Tube
        *d O-ring
        *e Fuel Pipe
        B000XM7 Pinch
        B000TT4 Pull

        Disengage the clamp to disconnect the fuel tube sub-assembly from the engine wire.

      3. 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.

      4. 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.

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

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