CAUTION:
When working with FIPG material, you must observe the follow-
ing items.

Using a razor blade and gasket scraper, remove all the old
FIPG material from the gasket surfaces.

Thoroughly clean all components to remove all the loose
material.

Clean both sealing surfaces with a non±residue solvent.

Apply FIPG in an approx. 1 mm (0.04 in.) wide bead along
the sealing surface.

Parts must be assembled within 10 minutes of application.
Otherwise, the FIPG material must be removed and reap-

8. FUEL SYSTEM
(a) When disconnecting the high pressure fuel line, a large
amount of gasoline will spill out, so observe these proce-
dures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch OFF.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.
(7) Reconnect the fuel pump connector.
(b) When connecting the flare nut or union bolt on the high
pressure pipe union, observe these procedures:
(1) Union Bolt Type:
Always use a new gasket.
(2) Union Bolt Type:
Tighten the union bolt by hand.
(3) Union Bolt Type:
Tighten the union bolt to the specified torque.
Torque: 29 N´m (300 kgf´cm, 22 ft´lbf)
(4) Flare Nut Type:
Apply a light coat of engine oil to the flare and tight-
en the flare nut by hand.
(5) Flare Nut Type:
Using SST, tighten the flare nut to the specified
torque.
SST 09631±22020
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque:
30 N´m (310 kgf´cm, 22 ft´lbf) for using SST
38 N´m (387 kgf´cm, 28 ft´lbf)
HINT:

(c) Observe these precautions when removing and 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, must apply spindle oil or gas-
oline on the place where a delivery pipe or an intake man-
ifold touches an O±ring of the injector.
(e) Observe these precautions when disconnecting the fuel
tube connector (quick type):
(1) Check if there is any dirt like mud on the pipe and
around the connector before disconnecting them
and clean the dirt away.
(2) Be sure to disconnect with hands.
(3) When the connector and the pipe are stuck, push
and pull the connector to free to disconnect and pull
it out. Do not use any tool at this time.
(4) Inspect if there is any dirt or the likes on the seal sur-
face of the disconnected pipe and clean it away.
(5) Prevent the disconnected pipe and connector from
damaging and mixing foreign objects by covering
them with a vinyl bag.
(f) Observe these precautions when connecting the fuel
tube connector (quick type):
(1) Check if there is any damage or foreign objects on
the connected part of the pipe.
(2) Match the axis of the connector with axis of the pipe,
and push in the connector until the connector
makes a ºclickº sound. In case the connections is
tight, apply little amount of new engine oil on the tip
of the pipe.
