INSTALLATION

1. Follow the procedure below and install the seal ring onto the fuel injector.

CAUTION:

• Handle the O-ring with bare hands. (Never wear gloves when handling O-ring.)

• Never apply engine oil to the seal ring.

• Never use solvents or similar substances to clean the seal ring.

a. Install the injector seal drift [SST: KV101197S0 ( — )] (A) onto

the fuel injector (1).

b. Set the seal ring (1) onto the injector seal drift [SST:

KV101197S0 ( — )] (A).

c. Install the seal ring (1) set in step 2 by inserting it straight into

the fuel injector as shown in the figure.

CAUTION:

When inserting the seal ring, never insert it further than the

groove portion of the fuel injector.

d. After installing the seal ring onto the fuel injector, install the

injector seal drift [SST: KV101197S0 ( — )] (A) onto the fuel

injector as shown in the figure. Turn it left and right by 90

° at a

time until it contacts the seal ring to settle the seal ring in place.

NOTE:

For correcting any elongation of the seal ring that occurs when

the injector seal drift is installed, use the drift so that the seal ring

is pressed and contracted.

2. Note the following points and install the O-ring and backup ring to the fuel injector.

CAUTION:

• Be sure to handle the O-ring with bare hands. (Never wear gloves.)

• Apply engine oil to the O-ring.

• Never use solvents or similar substances when cleaning the O-ring seal.

FUEL INJECTOR

• Check that the O-ring and its mating part are free of foreign material.

• When installing O-ring, never scratch it with tool or fingernail. Also never twist or stretch O-ring.

If O-ring is stretched while being attached, never insert it immediately.

• Insert O-ring straight onto fuel tube. Never decenter or turn it.

• Both the fuel rail adapter and backup ring (1) have a

tapered cross-section shape. Therefore, be careful of the

orientation when installing them.

3. Follow the procedure below and install the fuel rail (2) to the fuel

injector (1).

a. Install the injector holder (5) onto the fuel injector.

CAUTION:

• Never reuse the injector holder. Always use a new one.

• Check that the injector holder does not contact the O-ring.

If the clip contacts the O-ring, replace the O-ring.

b. With the injector holder installed, insert the fuel injector into the

fuel rail.

• Check that the axis is lined up when inserting.

• Insert so that the fuel tube projection (A) is aligned with the

notch (B).

c.

Check that the fuel injector is securely installed, and does not

turn or come out.

• Check that the projection on the fuel injector is fastened into

the fastening groove on the fuel rail.

4. Install the fuel injector assembly into the cylinder head installation hole.

CAUTION:

Be careful to prevent contact with the end of the injector nozzle.

• Tighten mounting bolts in two steps in the numerical order

shown in the figure.

5. If the fuel rail pressure sensor is removed, install it.

CAUTION:

Apply oil to the threads of the fuel rail pressure sensor before installing.

6. Connect the fuel rail pressure sensor harness connector.
7. Connect the fuel injector harness connector.

8. Install the fuel rail insulator.

CAUTION:

• Because the part on the rear end of the fuel rail which covers the fuel rail adapter is a shape that

can be moved easily, never remove it before assembling.

• Install the insulator so that it is underneath the intake manifold flange.

9. Install removed parts in the reverse order of removal.

INSPECTION AFTER INSTALLATION

Fuel Leakage Inspection

Check for fuel leakage according to the following procedure.
1. Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel

leakage at the locations where parts are removed and reinstalled.

NOTE:

Use a mirror or other means to check locations that cannot be seen directly.

2. Start the engine, increase the engine speed, and check again for fuel leakage at the locations where parts

are removed and reinstalled.

CAUTION:

Be careful of burns when checking.
