FUEL SYSTEM 5-3
FUEL LINE
REMOVAL/INSTALLATION
Remove or install the fuel hoses with the special attention to the following steps.
!
The components after the high pressure fuel pump remain pressurized at all times.
To protect against fuel spray, relieve fuel line pressure before disconnecting or removing compo-
nents. (See the page 5-2.)
#
• Do not over-bend (kink) or twist hoses when installing.
• When installing hose clips, position tabs to avoid contact with other parts.
• Be sure that hoses do not contact rods, levers or other components with engine either op-
erating 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 the fuel hose routing. (See the page 10-8 and 10-9.)
•
Check for fuel leakage.
FUEL LEAKAGE CHECK PROCEDURE
After performing any fuel system service, always be sure that
there is not fuel leakage by checking as follows.
1. Squeeze the fuel primer bulb until you feel resistance.
2. Turn the ignition switch “ON” for 3 seconds (to operate the
fuel pump), then turn it “OFF”.
Repeat this (ON and OFF) procedure 3 or 4 times to pressur-
ize the fuel system.
3. Once pressurized, check all connections and components for
any signs of leakage.
