the fuel system during which there may be fuel leakage,
there should be no welding, smoking, open flames, etc.,
in the area.

Prior to removing the electric fuel pump, the following
check should be performed to determine that removal is
necessary.
1. Turn the ignition switch ON and listen for a momen-
tary "whirring" sound of the pump building pressure.
If the sound is heard (10 seconds), no electrical
checks are necessary. Turn the ignition switch OFF.
