• Insert until you hear a “click” sound and actually feel the engagement.

• To avoid misidentification of engagement with a similar sound, be sure to perform the next step.

d. Pull quick connector by hand holding position. Check it is completely engaged (connected) so that it does

not come out from fuel tube.

e. Install quick connector cap (3) to quick connector.

• 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.

f.

Secure fuel feed hose to clamp of quick connector cap.

8. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

Check For Fuel Leaks

1. Turn ignition switch “ON” with the engine stopped. With fuel pressure applied to fuel piping, check for fuel

leaks at connection points. Repair as necessary.

NOTE:

Use mirrors for checking at points out of clear sight.

2. Start the engine. With engine speed increased, check again for fuel leaks at connection points. Repair as

necessary.

WARNING:

Do not touch the engine immediately after stopped, as the engine becomes extremely hot.

NOTE:

Use mirrors for checking on connections out of the direct line of sight.

• Perform procedures for “Throttle Valve Closed Position Learning” after finishing repairs. Refer to 

EC-

142, "Work Procedure"

.

• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after

finishing repairs. Refer to 

EC-143, "Work Procedure"
