CAUTION:

Never perform work on fuel system components near any possible ignition sources.
Vaporized fuel could ignite, resulting in a serious accident.

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.

PROCEDURE

PRECAUTION

Note

After turning the engine switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work.

REMOVE NO. 2 FUEL PIPE SUB-ASSEMBLY
CAUTION:

To prevent serious injury due to fuel spray from the high-pressure fuel lines, always discharge fuel system pressure before removing any fuel system components.
1. Front
  
  Using a 17 mm union nut wrench, loosen the 2 union nuts of the No. 2 fuel pipe sub-assembly.
2. Remove the No. 2 fuel pipe sub-assembly from the fuel delivery pipe with sensor assembly LH and fuel delivery pipe RH.

REMOVE FUEL DELIVERY PIPE WITH SENSOR ASSEMBLY LH

Disconnect the fuel pressure sensor connector.

Note

Do not pull the wire harness of the fuel pressure sensor excessively.
Front

Remove the bolt and detach the clamp to disconnect the No. 7 engine wire from the fuel delivery pipe with sensor assembly LH.

	Bolt
	Nut
	Front

Remove the 2 bolts and 2 nuts.

Front

Using an E8 "TORX" socket wrench, remove the 2 stud bolts from the cylinder head LH.
Front

With the connectors still connected, disconnect the fuel delivery pipe assembly LH.
Note
- Make sure that the fuel delivery pipe is disconnected from the fuel delivery pipe assembly LH.
- Be extremely careful not to touch or strike the tips of the fuel injector assemblies.
- Pull and remove the fuel delivery pipe in a straight line without tilting it.
Disconnect the 3 fuel injector connectors and remove the No. 7 engine wire.

REMOVE FUEL DELIVERY PIPE RH

Remove the bolt.
Front

Remove the bolt and detach the clamp to disconnect the No. 6 engine wire from the fuel delivery pipe RH.

	Bolt
	Nut
	Front

Remove the 2 bolts and 2 nuts.

With the connectors still connected, disconnect the fuel delivery pipe RH.
Note
- Be extremely careful not to touch or strike the tips of the fuel injector assemblies.
- Pull and remove the fuel delivery pipe RH in a straight line without tilting it.
Disconnect the 3 injector connectors and remove the No. 6 engine wire.

REMOVE FUEL INJECTOR ASSEMBLY
1. *1 No. 2
  
  Fix the fuel delivery pipe in a vise between aluminum plates.
  Note
  - Do not tighten the vise more than necessary.
  - Do not damage the fuel injector assemblies.
2. Remove the fuel injector assemblies from the fuel delivery pipe assembly LH and fuel delivery pipe RH.
  Note
  - When removing an injector, pull the injector straight out to avoid damaging the O-ring seal surfaces of the fuel delivery pipe assembly LH and fuel delivery pipe RH.
  - After removing the fuel injector assembly, check that the O-ring, No. 1 fuel injector back-up ring and No. 3 fuel injector back-up ring are not remaining on the fuel delivery pipe. If any of the parts remain on the fuel delivery pipe, remove them.
  - Attach a label to the removed fuel injector assembly to distinguish it from other cylinders.
3. Remove the nozzle holder clamp from each fuel injector assembly.
4. Using needle nose pliers, remove the No. 3 fuel injector back-up ring from each fuel injector assembly.
  
  Note
  
  Do not damage the area that contacts the O-ring.
5. Remove the O-ring and No. 1 fuel injector back-up ring from each fuel injector assembly.
6. Remove the C-ring and injector vibration insulator from each fuel injector assembly.
REMOVE FUEL INJECTOR SEAL
1. Using the tips of a pair of needle nose pliers, pinch and pull one of the fuel injector seals at several points to stretch it. Repeat this for the other fuel injector seal.
  Note
  
  Excessively pinching the fuel injector seal may damage the groove of the fuel injector assembly.
  
  If a fuel injector assembly is dropped or the tip of the fuel injector assembly is struck, replace it with a new one.
2. Remove the fuel injector seal from each fuel injector assembly.
