Fuel System

1. When disconnecting the high fuel pressure line, a large amount of gasoline will spill out. so observe the following procedures:
- Remove the luggage compartment trim cover.
- Disconnect the fuel pump connector.
- Start the engine. After the engine has stopped on its own, turn the ignition switch to LOCK.





- Put a container under the connection.
- Slowly loosen the connection.
- Disconnect the connection.
- Plug the connection with a rubber plug.
- Reconnect the fuel pump connector.
- Reinstall the luggage compartment trim cover.





2. When connecting the flare nut or union bolt on the high pressure pipe union, observe the following procedures:

Union Bolt Type:
- Always use a new gasket.
- Tighten the union bolt by hand.
- Tighten the union bolt to the specified torque.

Torque: 29 Nm (22 ft lb)





Flare Nut Type:
- Apply a light coat of engine oil to the flare nut and tighten the flare nut by hand.
- Using SST 09631-22020, tighten the flare nut to specified torque.

Torque: 30 Nm (22 ft lb)

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





3. Observe the following precautions when removing and installing the injectors.
- Never reuse the 0-ring.
- When placing a new 0-ring on the injector, take care not to damage it in any way.
- Coat a new 0-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 performing any maintenance anywhere on the fuel system.
- Using SST 09843-18020, connect terminals +B and FP of the DLC1.
- With engine stopped. turn the ignition switch ON.





- Pinch the fuel return hose.
The pressure in the high pressure line will rise to approx. 392 kPa (4 kgf/cm2, 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.

- Turn the ignition switch to LOCK.





- Remove SST 09843-18020 from the DLC1.
