Fuel Pressure Release: Service and Repair
FUEL SYSTEMa. When disconnecting the high fuel pressure line, a large amount of gasoline will spill out, so observe these procedures:
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 union bolt (fuel pressure pulsation damper) on the high pressure pipe union, observe these procedures:
1. Always use 2 new gaskets.
2. Tighten the union bolt by hand.
3. 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. When connecting the flare nut on the high pressure pipe union, observe these procedures:
1. Apply a light coat of engine oil to the flare nut, and tighten the flare nut by hand.
2. Using SST, tighten the flare nut to the specified torque.
SST 09023-12700
NOTE: Do not rotate the fuel main tube, when tightening the flare nut.
Torque: 32 N.m (330 kgf.cm, 24 ft.lbf)
HINT: Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
