ing out retainer tabs.
i. With the sleeve side of quick connector release facing to quick connector, install the quick connector
release onto fuel tube.
ii. Insert the quick connector release (A) into quick connector (2)
until sleeve (B) contacts and goes no further. Hold quick connec-
tor release on that position.

quick connector. Hold quick connector release where it
contacts and goes no further.
iii. Draw and pull out quick connector straight from fuel tube (1).
CAUTION:
 Pull quick connector (E) holding position (D) as shown in
the figure.
 Never pull with lateral force applied. O-ring inside quick connector may be damaged.

 Avoid fire and sparks.
 Keep parts away from heat source. Especially, be careful when welding is performed around
them.
 Never expose parts to battery electrolyte or other acids.
 Never bend or twist connection between quick connector and fuel feed hose (with damper) dur-
ing installation/removal.
 To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely 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 new O-ring straight into fuel tube. Never twist it.
b. Install spacer (3) to fuel damper (4).
c. Insert fuel damper straight into fuel tube.
CAUTION:
 Insert straight, making sure that the axis is lined up.
 Never pressure-fit with excessive force.
 Insert fuel damper until (B) is touching (A) of fuel tube.

(C) of clip.
CAUTION:
 Never reuse clip. Replace it with 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 (1) with clip attached.
 Insert it while matching it to the axial center.
 Insert fuel injector so that protrusion (A) of fuel tube matches
cutout (B) of clip.
 Check that fuel tube flange (G) is securely fixed in flange fixing
groove (D) on clip.
c. Check that installation is complete by checking that fuel injector
does not rotate or come off.

Check on Fuel Leakage
1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, check there
are no fuel leakage at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start the engine. With engine speed increased, check again that there are no fuel leakage at connection
points.
CAUTION:
Never touch the engine immediately after stopped, as the engine becomes extremely hot.
