FUEL SYSTEM
1. When disconnecting the high pressure fuel line, a large
amount of gasoline will spill out, so observe the following
procedures:
(a) Disconnect the fuel pump connector.
(b) Start the engine. After the engine has stopped on its own,
turn off the ignition switch.
(c) Put a container under the connection.
(d) Slowly loosen the connection.
(e) Disconnect the connection.
(f) Plug the connection with a rubber plug.
(g) Reconnect the fuel pump connector.
2. When connecting the flare nut or union bolt on the high
pressure pipe union, observe the following procedures:
Union Bolt Type:
(a) Always use a new gasket.
(b) Tighten the union bolt by hand.
(c) Tighten the union bolt to the specified torque.
Torque: 29 NVm (300 kgfVcm, 22 ftVlbf)
Flare Nut Type:
(a) Apply a light coat of engine oil to the flare nut, and tighten the
flare nut by hand.
(b) Using SST, tighten the flare nut to specified torque.
SST 09631±22020
Torque: 30 NVm (310 kgfVcm, 22 ftVlbf)
HINT: Use a torque wrench with a fulcrum length of 30 cm
(11.81 in.). EG±262

3. Observe the following precautions when removing and
installing the injectors.
(a) Never reuse the O±ring.
(b) When placing a new O±ring on the injector, take care not to
damage it in any way.
(c) Coat a new O±ring with spindle oil or gasoline before
installing±never use engine, gear or brake oil.
4. Install the injector to the delivery pipe and intake manifold as
shown in the illustration.
5. Check that there are no fuel leaks after doing maintenance
anywhere on the fuel system.
(a) Using SST, connect terminals +B and FP of the DLC 1.
SST 09843±18020
(b) With engine stopped, turn the ignition switch ON.
(c) 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.
(d) Turn the ignition switch OFF.
(e) Remove the SST from the DLC1.
