Electric Fuel Pump
REMOVAL AND INSTALLATION
Fuel Filters
NOTE: Ignition switch (11572) must be in OFF position before removing the filter.
Fuel is filtered at two locations on Aerostar and Ranger vehicles.
In-Tank
A nylon filter element (inlet filter sock) is mounted on the in-tank electric fuel pump inlet inside the fuel tank
and is used to protect the fuel pump from fuel tank contaminants.
The in-tank filter is not serviced separately. To service the in-tank filter, replace the fuel pump and sender
assembly.
In-Line
The fuel filter on MFI applications provides extremely fine filtration to protect the small metering orifices of
the fuel injector nozzle tips (9E527). The filter is a one-piece construction which cannot be cleaned. If the
filter becomes clogged or restricted, it should be replaced.
MFI engines with electric fuel pumps (9350) have an in-line fuel filter, located on the left frame (5005) or
body side rail downstream from the fuel pump.
The in-line fuel filter should last the life of the vehicle under normal driving conditions. If the filter does need
to be replaced, proceed as follows.
Removal
CAUTION: If the fuel filter is being serviced with the rear of the vehicle higher than the front, or
if the fuel tank (9002) is pressurized, fuel leakage (or siphoning from the tank fuel) from the lines
could occur. To prevent this condition, maintain the vehicle front end at or above the level of the rear
of vehicle. Also, relieve tank pressure by loosening the fuel tank filler cap (9030). Fuel tank filler cap
should be retightened after pressure is relieved. If vehicle is warm, change the fuel filter before the
pressure rebuilds.
1. NOTE: Refer to installation figures under Removal and Installation,
Lines in this section.
Shut engine (6007) off. Depressurize fuel system. Refer to Service Procedures,
Pressure Relief in this section. Use caution to prevent combustion from fuel spillage.
2. Raise vehicle on hoist.
3. Remove push connect fittings at both ends of fuel filter as described in Removal and Installation,
Push Connect Fittings
4. NOTE: The "flow" arrow direction should be positioned as installed in bracket to make sure of
proper flow of fuel through the replacement filter.
