1. REMOVE NO.2 CYLINDER HEAD COVER
2. REMOVE CYLINDER HEAD COVER




3. DISCONNECT FUEL TUBE
a. Remove the fuel pipe clamp.
b. Disconnect the fuel tube (fuel tube connector) from the fuel pipe.

NOTE: Be careful not to drop the injectors when removing the delivery pipe.

a. Disconnect the 4 injector connectors from injector.
b. Remove the 3 bolts and delivery pipe together with the 4 injectors and fuel pipe.
c. Remove the 2 spacers from the cylinder head.
d. Pull out the 4 injectors from the delivery pipe.
e. Remove the O-rings and grommets from each injector.
