(b) Observe the following precautions when removing and
installing fuel injectors.
NOTICE:
Never reuse the O±ring.
(1) When installing a new O±ring on the injector, be
careful not to damage the injector.
(2) Coat the new O±ring with grease or gasoline before
installing. Never use engine oil, gear oil or brake oil.
(c) Install the injector to the delivery pipe and cylinder head
as shown in the illustration. Before installing the injector,
be sure to apply grease or gasoline on the place where
the delivery pipe contacts the O±ring of the injector.
(d) Observe these precautions when disconnecting the fuel
delivery pipe.
HINT:
The structure of the metallic connector is as shown in the il-
lustration on the left.
(1) Remove the fuel pipe clamp No.2.
(2) Find the metallic connector of the fuel tube assem-

introduced, cover them with a vinyl or plastic bag.
(f)Observe these precautions when connecting the fuel tube connectors (Quick Type):
(1)Check that there is no damage or foreign objects in
the connected part of the pipe.
(2)Match the axis of the connector with the axis of the pipe, and push into the connector until the connec-
tor makes a ºclickº sound. If the connection is tight,
apply little amount of fresh engine oil on the tip of the
pipe.
(3)After having finished the connection, check if the
pipe and the connector are securely connected by
pulling on them.
(4)Check for fuel leaks.
4.CHECK FOR FUEL LEAKS
(a)Check that there are no fuel leaks after doing maintenance anywhere on t\
