MAINTENANCE
Item 12 – Fuel Filters
One method of determining when
filters are plugged to the extent that
they need replacing is based on the
fuel pressure at the cylinder head fuel
inlet fitting and the inlet restriction
at the fuel pump. In a clean system
the maximum pump inlet restriction
should not exceed 6 inches of mercury
(20.3 kPa). In a dirty system it must
not exceed 12 inches of mercury (41
kPa).
At normal operating speed and with
the standard .080 inch restriction
fittings, the fuel pressure is 55 – 70
psi (375 – 483 kPa). Change the fuel
filters whenever the inlet restriction
at the pump reaches 12 inches of
mercury (41 kPa) at normal operating
speeds and whenever the fuel pressure
at the inlet fitting falls to the minimum
fuel pressure of 6 inches of mercury
(20.3 kPa).
NOTE:
Filter change intervals may be
shortened to conform with established
preventive maintenance schedules,
but should never be extended.
Fuel Pro® 382 Filters — Install
new Fuel Pro® 382 primary fuel filter
elements when the fuel level in the
see-thru cover reaches the top of the
element or after one year of service,
whichever comes first.

Spin-On Filters — Install new
spin-on primary and secondary fuel
filter elements on vehicle engines
every 15,000 miles (24,000 km) or
every six months, whichever comes
first. See Figure 17.
Figure 17
Install new spin-on filter elements
on non-vehicle engines every 150
hours. Replace spin-on filter elements
immediately if plugging is indicated,
regardless of mileage or hour intervals.
Item 13 – Water Pump and
Coolant Inhibitor Element
Check the water pump and the coolant
inhibitor element.
Water Pump Drain Hole — The
water pump drain hole should be
inspected every 6 months to make
sure it is open. A small chemical
build-up or streaking at the drain hole
may occur. This is not an indication
