(NOTE: In inseallations with fuel tanks located above engine
height, to prevent fuel syphoning when the filter is
removed, shut the fuel OFF at the tank shut-off during this
servicing. Turn the fuel back ON, once a new filter has been
installed. Install the new filter simply by applying some

the ignition key ON to activate the fuel pump. This will
prime the filter and vent any air from it.)

used to accomplish this same function without having to turn
the ignition key ON. (It takes approximately 20 pumps to
prime the filter.)
