Using SST, tighten the union bolt to the specified
torque.

SST

09612–24014  (09617–24011)

Torque:
33 N·m (340 kgf·cm, 24 ft·lbf) for use with SST
39 N·m (400 kgf·cm, 29 ft·lbf)

HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).

(c)

Observe the following precautions when removing or
installing the injectors.
(1)

Never reuse the O–ring.

(2)

When placing a new O–ring on the injector, take
care not to damage it in any way.

(3)

Coat a new O–ring with spindle oil or gasoline be-
fore installing. Never use engine, gear or brake oil.

(d)

Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
Before installing the injector, apply spindle oil or gasoline
on the place where the delivery pipe or the intake man-
ifold touches the O–ring of the injector.

(e)

Observe the following when disconnecting the fuel tube
connector (quick type):
(1)

Check if there is any dirt in the pipe and around the
connector before disconnecting the fuel tube con-
nector. If necessary, clean the dirt away.

(2)

Disconnect the fuel pipe clamp from the connector.

(3)

Be sure to disconnect them by hand.

(4)

When the connector and the pipe are stuck, push
and pull the connector. Then disconnect and pull it
out. Do not use any tools at this time.

(5)

Check if there is any dirt or other foreign matter on
the seal surface of the disconnected pipe. If neces-

Check if there is any damage or foreign objects in
the connected part of the pipe.

(2)

Match the axis of the connector with the axis of the
pipe, and push into the connector until a ”click”
sound is heard. If the connection is tight, apply a
small amount of fresh engine oil on the tip of the
pipe.

(3)

After finishing the connection, pull the pipe and the
connector to ensure it is secure.

SPD.

(4)

Please refer to the hand–held tester operator’s
manual for further details.

(5)

Pinch the fuel return hose.
The pressure in the high pressure line will rise to
approx. 392 kPa (4 kgf/cm

2

, 57 psi). In this state,

check to see that there are no leaks from any part
of the fuel system.

NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.

(6)

Turn the ignition switch OFF.
