5. Remove fuel injector from fuel tube.
●Release clip and remove it.
●Pull fuel injector straight out of fuel tube.
CAUTION:
●Be careful not to damage nozzle part.
●Avoid any impact such as a dropping.
●Do not disassemble or adjust it.
INSTALLATION
1. When installing O-ring to fuel injector, follow instructions described below.
CAUTION:
●Handle O-ring with bare hands. Never wear gloves.
●Lubricate O-ring with new engine oil.
●Do not clean O-ring with solvent.
●Make sure that O-ring and its mating part are free of foreign material.
●Be careful not to scratch it with a tool or fingernails during installation. Also be careful not to
twist or stretch O-ring. If O-ring is stretched while being attached, do not insert it into fuel tube
immediately.
●Insert O-ring straight into fuel tube. Do not angle or twist it.
2.
Install fuel injector to fuel tube with the following procedure.
a. Insert clip into clip mounting groove on fuel injector.
●Insert clip so that lug “A” of fuel injector matches notch “A” of
the clip.
CAUTION:
●Do not reuse clip. Replace it with a new one.
●Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.
●Insert it while matching it to the axial center.
●Insert fuel injector so that lug “B” of fuel tube matches notch
“B” of the clip.
●Make sure that fuel tube flange is securely fixed in flange fix-
ing groove on clip.
c. Make sure that installation is complete by checking that fuel
injector does not rotate or come off.
