When separating fuel feed hose and fuel tube connection, disconnect quick connector as follows:
Remove quick connector cap from quick connector.
Disconnect quick connector from fuel tube as follows:
CAUTION: Disconnect quick connector by using the quick connector release (commercial service tool: J-45488), not by picking out retainer tabs.
With the sleeve side of quick connector release facing to quick connector, install the quick connector release onto fuel tube.
Insert the quick connector release (A) into quick connector (2) until sleeve (B) contacts and goes no further. Hold quick connector release on that position.
C : Insert and retain
CAUTION: Inserting quick connector release hard will not disconnect quick connector. Hold quick connector release where it contacts and goes no further.
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.
Prepare container and cloth beforehand as fuel will leakage out.
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) during installation/removal.
To keep clean the connecting portion and to avoid damage and foreign materials, cover them completely with plastic bags, etc. (A) or something similar.
Install new O-ring (2) to fuel tube (1) as shown. When handling new O-ring, be careful of the following caution:
CAUTION:
Handle O-ring with bare hands. Never wear gloves.
Lubricate O-ring with new engine oil.
Never clean O-ring with solvent.
Check 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 new O-ring straight into fuel tube. Never twist it.
Install spacer (3) to fuel damper (4).
Insert fuel damper straight into fuel tube.
CAUTION:
Insert straight, checking that the axis is lined up.
Never pressure-fit with excessive force.
Reference value : 130 N (13.3 kg, 29.2 lb)
Insert fuel damper until (B) is touching (A) of fuel tube.
Tighten bolts evenly in turn.
After tightening bolts, check that there is no gap between fuel damper cap (5) and fuel tube.
Install new O-rings to fuel injector paying attention to the following.
CAUTION:
Upper and lower O-ring 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.
Check 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 injector. Never decenter or twist it.
Connect quick connector between fuel feed hose and fuel tube connection with the following procedure:
Check no foreign substances are deposited in and around fuel tube and quick connector, and no damage on them.
Thinly apply new engine oil around fuel tube from tip end to spool end.
Align center to insert quick connector straightly into fuel tube.
Insert quick connector (1) to fuel tube until top spool (2) is completely inside quick connector, and 2nd level spool (3) exposes right below quick connector.
B : Fitted condition
White arrow indicates Upright insertion
CAUTION:
Hold (A) position as shown in the figure when inserting fuel tube into quick connector.
Carefully align center to avoid inclined insertion to prevent damage to O-ring inside quick connector.
Insert until you hear a "click" sound and actually feel the engagement.
To avoid mis-identification of engagement with a similar sound, be sure to perform the next step.
Pull quick connector by hand holding position. Check it is completely engaged (connected) so that it does not come out from fuel tube.
Install quick connector cap (3) to quick connector.
1 : Fuel feed hose
2 : Fuel tube
B : Upper view
Install quick connector cap with arrow (A) on surface facing in direction of quick connector (fuel feed hose side).
CAUTION: If quick connector cap cannot be installed smoothly, quick connector may have not been installed correctly. Check connection again.
Secure fuel feed hose to clamp of quick connector cap.
Installation is in the reverse order of removal.
Inspection AFTER INSTALLATION
Make sure there is no fuel leakage at connections as follows:
Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at connections.
Start the engine and rev it up and check for fuel leaks at connections.
CAUTION: Do not touch engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
