10. Remove fuel injector from fuel tube with the following procedure:
a. Open and remove clip.
b. Remove fuel injector from fuel tube by pulling straight.
CAUTION:

Be careful with remaining fuel that may go out from fuel tube.

Be careful not to damage fuel injector nozzle during removal.

Never bump or drop fuel injector.

Never disassemble fuel injector.
INSTALLATION
1. Note the following, and install O-rings to fuel injector.
CAUTION:

Upper and lower O-rings are different. Be careful not to confuse them.

Handle O-ring with bare hands. Never wear gloves.

Lubricate O-ring with new engine oil.

Never clean O-ring with solvent.

Make sure that O-ring and its mating part are free of foreign material.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, never insert it quickly
into fuel tube.

Insert O-ring straight into fuel tube. Never twist it.

2. Install fuel injector (4) to fuel tube (1) with the following proce-
dure:
a. Insert clip (2) into clip groove (F) on fuel injector.
