returned to the fuel tank.
• The fuel lubricates the injectors, so it is normal
for some to bleed-off.
6. A fuel shut-off solenoid on the fuel injector pump
stops the fuel flow when the key switch is turned-
off. It makes an audible click when energized or
de-energized. See Figure 8.97.

ments, remove the rear fender and splash

of the fender to the upright that the rear tube of
the OPS mounts to using a 5/16” wrench.
