Introduction
Winslow® filter elements must be changed
periodically to assure the high level of filtering
efficiencies required. We recommend that the
elements be changed when the pressure differential
across the filter reaches the maximum allowable
pressure drop as recommended by the engine
manufacturer. Excessive pressure differential across
the elements could result in reduced flow.
Winslow Fuel Filters are designed to be mounted
on the pressure side of a low pressure (< 75 PSI
(517.1 kPa)) fuel pump, however they can be
mounted on the suction side of a low pressure pump
if sized properly. Housing restriction for suction side
applications must be less than 1 PSID (6.9 kPa).
Pump specifications regarding inlet restriction
should be followed and supersede other general
recommendations.
To determine the correct pressure differential:
Note the pressure drop between the filter inlet •
and outlet when clean elements are installed
and the system is up to normal operating flow,
temperature, and pressure.
Periodically check the gradual increase of •
the filter differential pressure as the filter
accumulates hours of operating service.
If no engine specification is known or given, filters
should be changed out at 5-7 PSID (34.5-48.3 kPa)
above initial differential pressure. Initial differential
pressure should be 2-3 PSID (13.8-20.7 kPa)(an
initial differential pressure less than 3 PSID
(20.7 kPa) is acceptable, but a smaller filter could
probably be used).
Servicing the Filter
Removing the Filter Elements
Shut off the flow to the filter. Isolate the filter, if 1.
possible, by closing the main upstream valve and
then the main downstream valve.
Shut off electrical power to any accessories 2.
attached to the vessel.
Remove the air vent plug to equalize the 3.
pressure in the tank.
Figure 1 – Removing the Air Vent Plug
Remove the “dirty oil” drain plug (upper plug) and 4.
completely drain the filter chamber.
E
CAUTION Fluid may be hot!
The filter design includes a sludge and water sump
section. A drain is provided at the bottom of the
sump for use when the elements require changing.

Figure 5 – Freeing the Internal Components
Loosen and remove the internal components, 9.
including the dirty elements (components vary
according to housing – see page 1). Pull the
elements straight up to remove. Dispose of the
elements in an environmentally responsible
manner, according to state and/or federal (EPA)
recommendations.

Place the cover UPSIDE DOWN on a clean work 7.
surface. Be careful not to nick or scratch the
bottom edge of the sealing surface.

to fall through the opening of the

clean outlet area.

Reassembling the Filter
Reinstall the internal components, including the 10.
new elements. Note the direction of the arrow
on each element and insert the proper end into
the housing first. If seal cups are included as
part of the internal components, they must be
reinstalled, as well.
Replace the O-ring cover seal. (If necessary, 12.
as long as there are no permanent surface
deformations, swelling, nicks, and cracks
present, the seal can be reused.)
Figure 9 – Replacing the O-Ring Cover Seal
Seat the O-ring cover seal into the flange groove.13.
Carefully replace the cover STRAIGHT DOWN 14.
and align the bolt slots in the cover flange with
the slots in the housing flange.

Figure 12 – Reinstalling the “Dirty Oil” Drain Plug
Refill the filter manually or by slowly opening the 17.
main upstream valve.
When the vessel is full, reinstall the vent plug.18.
Figure 13 – Replacing the Vent Plug
Increase the pressure in the filter slowly. Inspect 19.
for leaks around the cover gasket area. If no
leaks are visible, increase to operating pressure.
Inspect for leaks again.20.
Reconnect electrical power to any accessories.21.
Slowly open the downstream valve, if applicable, 22.
placing the unit in service.
Read and record the pressure differential of the 23.
clean elements.
The filter is now operational.24.
