Section 10-01: Fuel Tank, Filter and Electric Fuel Pump | 1993 Mustang Workshop Manual |
Fuel is filtered at three locations on all applications.
Fuel Pump Inlet Filter
A nylon filter element is mounted on the electric fuel pump inlet inside the fuel tank and is used to protect the fuel pump from fuel tank contaminants.
Fuel Filter, In-Line
The purpose of the in-line fuel filter is to provide filtration to protect the small metering orifices of the injector nozzles. The filter is located downstream of the electric fuel pump and is mounted on the underbody. The fuel filter is a one-piece construction which cannot be cleaned. If it becomes clogged it must be replaced.
NOTE: When replacing fuel filters, use the filter specified for the engine being serviced.
Injector Filter—Screen
An injector filter is located at the top of each injector and is not
serviceable. If injector screen becomes clogged, the complete injector assembly
must be replaced. Refer to Section 03-04A 2.3L or 03-04B 5.0L for fuel injector
information.
