REMOVAL / INSTALLATION
Pay special attention to the following steps when removing or
installing fuel hoses.
The components after the high pressure fuel pump re-
main pressurized at all times.
To protect against fuel spray, relieve fuel line pressure
before disconnecting or removing components.
• Do not over bend (kink) or twist hoses when install-
ing.
• When installing hose clips, position tabs to avoid
contact with other parts.
• Be sure hoses do not contact rods, levers or other
components with engine either operating or at rest.
• Extreme care should be taken not to cut, abrade or
cause any other damage to hoses.
• Use care not to excessively compress hoses when
tightening clamps.
NOTE:
• Check fuel hose routing. (See page 10-8 and 10-11)
• Check for fuel leakage.

FUEL LEAKAGE CHECK PROCEDURE

After performing any fuel system service, always be sure there
is not fuel leakage by checking as follows.
1. Squeeze fuel primer bulb until you feel resistance.
2. Turn ignition switch "ON" for 3 seconds (to operate fuel
