Fuel System Safety Procedures

1. When disconnecting the high pressure fuel line, a large amount of gasoline will spill out, so observe the following procedures:





^ Put a container under the connection.
^ Slowly loosen the connection.
^ Disconnect the connection.
^ Plug the connection with a rubber plug.
2. When connecting the flare nut or union bolt on the high pressure pipe union, observe the following procedures:

Union Bolt Type:





^ Always use 2 new gaskets.
^ Tighten the union bolt first by hand.
^ Then tighten the union bolt to the specified torque.

Torque: 30 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, tighten the flare nut to specified torque. (SST 09631-22020)

Torque: 28 Nm (21 ft lb) for fuel pump side.
30 Nm (22 ft lb) for others.

NOTE: Do not rotate the fuel pipe, when tightening the flare nut.





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 on the fuel system.





^ Using SST, connect terminals +B and FP of the Data Link Connector (DLC) 1. (SST 09843-18020)





^ 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 (57 psi). In this state, check to see that there are no leaks from any part of the fuel system.

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





^ Turn the ignition switch to LOCK.





^ Remove the SST from the DLC1. (SST 09843-18020)
