NOTE:
Filter change intervals may be
shortened to conform with established
preventive maintenance schedules,
but should never be extended.
One method of determining when
fi
lters are plugged to the extent that
they need replacing is based on the
fuel pressure at the cylinder head fuel
inlet
fi
tting. Fuel pressure should be
no less than 60 psi (414 kPa) at normal
operating speed.
Change the fuel
fi
lters whenever the
fuel pressure at the inlet
fi
tting falls
below this level.
All information subject to change without notice.
