(a) 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.

(1) Always use 2 new gaskets.
(2) Tighten the union bolt by hand.
(3) Tighten the union bolt to the specified torque.

Torque: 29 N.m (300 kgf.cm, 21 ft.lbf)





(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 specified torque. SST 09631-22020

NOTICE: Do not rotate the fuel pipe, when tightening the flare nut. Torque: 28 N.m (285 kgf.cm, 21 ft.lbf) for using SST
