FUEL INJECTOR AND FUEL TUBE

6. Remove the fuel tube assembly bolts in the reverse order as

shown, then remove the fuel tube and fuel injectors as an

assembly.

7. Remove the fuel injectors from the fuel tube.

• Release the clip and remove the fuel injector.

• Pull fuel injector straight out of the fuel tube.

CAUTION:

• Be careful not to damage the nozzle.

• Avoid any impact, such as dropping the fuel injector.

• Do not disassemble or adjust the fuel injector.

INSTALLATION

1. Install new O-rings on the fuel injector, the fuel side black O-ring and the nozzle side green O-ring.

CAUTION:

• Upper and lower O-rings are different. Be careful not to confuse them.

- Fuel tube side: black O-ring

- Nozzle side: green O-ring

• Lubricate the O-rings lightly with new engine oil.

• Handle O-rings with bare hands only. Do not wear gloves.

• Do not clean O-rings with solvent.

• Make sure that O-ring and its mating part is free of foreign material.

• Be careful not to scratch O-rings during installation. 

• Do not twist or stretch the O-ring. If the O-ring was stretched while it is attached, do not insert it

into the fuel tube immediately.

2. Install the fuel injector (5) into the fuel tube (1) with the following

procedure:

• Do not reuse the clip (3), replace it with a new one.

• Insert the new clip (3) into the clip mounting groove (F) on fuel

• Insert the clip (3) so that projection (E) of fuel injector (5)

matches notch (C) of the clip (3).

• Fuel tube side: black O-ring (2)

• Nozzle side: green O-ring (4)

3. Insert fuel injector (5) into fuel tube (1) with clip (3) attached.

• Insert it while matching it to the axial center.

• Insert fuel injector (5) so that projection (A) of fuel tube (1)

matches notch (B) of the clip (3).

• Make sure that fuel tube flange (G) is securely fixed in flange

fixing groove (D) on the clip (3).

• Make sure that installation is complete by checking that fuel

injector (5) does not rotate or come off.
