GDI  – Fuel Injector

13A-135

2.

While being careful not to damage the O-ring, turn the
fuel injector to the left and right and connect it to the
delivery pipe. After connecting, check that the fuel injector
turns smoothly.

3.

If the fuel injector does not turn smoothly, the cause may
be that the O-ring is getting caught. Remove the fuel
injector, check the O-ring for damage and re-connect the
fuel injector to the delivery pipe assembly and then
re-check.

4.

Align the Fuel injector mating mark with the delivery pipe
mating mark.

5.

Install the injector gasket and insulator to the cylinder
head.

6.

Install the delivery pipe and fuel injector assembly to the
cylinder head, and then temporarily tighten mounting bolts.

7.

Install the injector holder and the injector washer then
tighten mounting bolts to the specified torque.

Tightening torque: 21 – 25 Nm

8.

Tighten the mounting bolts to temporarily tighten the
delivery pipe and the fuel injector assembly according
to the illustrated sequence to the specified torque.

Tightening torque: 11 – 13 Nm

BACK-UP RING B/O-RING/BACK-UP RING
A/FUEL PIPE INSTALLATION

1.

Install the back-up rings and the O-ring as shown in the
illustration.
Caution
(1) Install the back-up ring B facing its cutaway

surface toward the opposite side of the O-ring
as shown in the illustration.

(2) Confirm the outer diameter of the back-up ring

A. Take care not to install the back-up ring for
the fuel pressure sensor by mistake. (Outer
diameter of the back-up ring A: 14.8 mm)

2.

Apply a small amount of fresh engine oil to the O-ring.

Caution
Take care not to let any of the engine oil get inside
the fuel pump (high pressure) or the delivery pipe.

3.

Insert the fuel pipe into the fuel pump (high pressure)
and the delivery pipe ports squarely. Insert the pipe
securely, being careful not to twisting it, and then tighten
the mounting bolts to the specified torque.

Tightening torque: 11 – 13 Nm

Be careful not to confuse this back-up ring with the
back-up ring A for the fuel injector or back-up ring A
for the fuel pipe. (External diameter of the back-up ring:
15.1 mm)

FUEL PRESSURE SENSOR/FLANGE
INSTALLATION

1.

Apply a small amount of fresh engine oil to the O-ring.

Caution
Take care not to let any of the engine oil get inside
the delivery pipe.

2.

Install the fuel pressure sensor so that the part number
label comes to the same direction shown in the illustration.
If the old fuel pressure sensor is reused, Install the sensor
to the delivery pipe using the mating mark made during
its removal.

Caution
If the fuel pressure sensor is replaced with a new
one, replace it together with the flange as a set.

O-RING/HIGH-PRESSURE FUEL HOSE
INSTALLATION

1.

Apply a small amount of new engine oil to the O-ring.

Caution
Do not let any engine oil get into the delivery pipe.

2.

While turning the high-pressure fuel hose to the right and
left, install the delivery pipe, while being careful not to
damage the O-ring. After installing, check that the hose
turns smoothly.

3.

If the hose does not turn smoothly, the O-ring is probably
being clamped. Disconnect the high-pressure fuel hose
and check the O-ring for damage. After this, re-insert the
delivery pipe and check that the hose turns smoothly.

4.

Tighten to the specified torque.

Tightening torque: 5.0 Nm
