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.

Remove the “dirty oil” drain plug (upper plug) and 4.
completely drain the filter chamber.

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.
