(b)Apply a light coat of spindle oil or gasoline on the place where a fuel delivery pipe contacts the O±ring.
(c)Push the fuel injector while twisting it back and forth to
install it to the fuel delivery pipe.
NOTICE:
Be careful not to twist the O±ring.
After installing the fuel injectors, check that they turn
smoothly. If not, reinstall it with a new O±ring.
8.INSTALL FUEL DELIVERY PIPE SUB±ASSY
(a)Install 4 new insulators and the 2 delivery pipe No. 1 spacers to the cylinder head.
(b)Place the fuel delivery pipe and the 4 fuel injectors togeth- er to the cylinder head.
NOTICE:
Be careful not to drop the fuel injectors when installing the
fuel delivery pipe.
(c)Temporarily install 2 bolts which are used to secure the fuel delivery pipe to the cylinder head.
(d)Check that the fuel injectors rotate smoothly.
If the fuel injectors do not rotate smoothly, the probable cause
is incorrect installation of O±ring. Replace with the O±ring.
(e)Tighten the 2 bolts. Torque: 20 N m (204 kgfcm, 15 ftlbf)
(f)Connect the 4 fuel injector connectors.
(g)Install the 2 wire harness clamps.
(h)Connect the ventilation hose.
9.CONNECT FUEL TUBE SUB±ASSY
(a)Push in the connector to the pipe until it makes ºclickº sound.
NOTICE:
Check if there is any damage or foreign objects on the
connected part.
After connecting, check if the connector and the pipe
are securely connected by pulling on them.
(b)Install the fuel pipe clamp.
