• Never clean O-ring with solvent.

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

material.

• Never scratch O-ring with tools or fingernails when

installing fuel rail connector.

• Insert new fuel rail connector straight into fuel rail. Never decenter or twist the fuel rail connec-

tor during insertion.

Inspection

INFOID:0000000012197276

INSPECTION AFTER INSTALLATION

Check for Fuel Leakage

1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, check that

there is no fuel leakage at connection points.

NOTE:

Use mirrors for checking at points out of clear sight.

2. Start the engine. With engine speed increased, check again that there is no fuel leakage at connection

points.

CAUTION:

Never touch the engine immediately after it is stopped because the engine is extremely hot.

d. Tighten fuel pressure sensor.

CAUTION:

• Before tightening fuel pressure sensor, securely install a hexagon tool.

• Never use impact applied fuel pressure sensor or gasket, such as dropped.

e. Tighten fuel rail pressure sensor again by using angle wrench [SST: KV10112100] and torque wrench.

(Angle tightening)

CAUTION:

• To check tightening angle, use angle wrench [SST: KV10112100]. Never judge the angle by visual

inspection.

• The torque value for the angle tightening must be 90 N·m (9.2 kg-m, 66 ft-lb) or less.

• If torque value reaches 90 N·m (9.2 kg-m, 66 ft-lb), then replace fuel rail pressure sensor with a

new one.

2. Install seal ring to fuel injector as per the following:

CAUTION:

• Handle seal ring with bare hands. Never wear gloves.

• Never apply engine oil to seal ring.

• Never clean seal ring with solvent.

tor and rotate clockwise and counterclockwise by 90

while

pressing seal ring to fit it.

NOTE:

Compress seal ring, because this operation is for rectifying

stretch of seal ring caused by installation and for preventing

sticking when inserting injector into cylinder head.

3. Install O-ring and backup ring to fuel injector. When handing

new O-ring and backup ring, paying attention to the following

caution items:

CAUTION:

• Do not reuse O-ring.

• Handle O-ring with bare hands. Never wear gloves.

• Lubricate O-ring with new engine oil.

• Never clean O-ring with solvent.

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

• When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to

twist or stretch O-ring. If O-ring was stretched while it was being attached, never insert it quickly

into fuel tube.

• Insert new O-ring straight into fuel rail. Never decenter or twist it.

• Always install the back up ring (1) in the right direction as

instructed.

4. Install fuel injector (1) to fuel rail (2) as per the following:

a. Install fuel injector holder (5) to fuel injector.

CAUTION:

• Never reuse fuel injector holder. Replace it with a new

one.

• Be careful to keep fuel injector holder from interfering

with O-ring. If interference occurs, replace O-ring.

b. Insert fuel injector into fuel rail with fuel injector holder attached.

• Insert it while matching it to the axial center.

• Insert so that protrusion (A) of fuel injector is aligned to cutout

(B).

Check that installation is complete by checking that fuel injector

does not rotate or come off.

• Check that protrusions of fuel injectors and fuel rail are aligned

with cutouts of clips after installation.

5. Install fuel rail and fuel injector assembly to cylinder head.
