Section 10-01A: Fuel Tank, Filters, Tubes and Electric Fuel Pump, Gasoline Engines | 1996 F-150, F-250, F-350, F-Super Duty and Bronco with Gasoline Engines Workshop Manual |
The in-line fuel filter (9155) provides filtration to protect the small metering orifices of the fuel injector nozzles. The fuel filter assembly is located on the left frame rail.
NOTE: The fuel filter should be changed at 24,000 km (15,000 miles) or 15-month intervals, and each time a fuel tank sending unit and pump is replaced. When the fuel filter needs to be replaced, proceed to Fuel Filter, In-Line in the Removal and Installation portion of this section.
If the fuel sending unit and pump is replaced, or the fuel system is contaminated with particles, the fuel filter should be replaced. If contamination of fuel is suspected, refill fuel tank (9002) with clean fuel, not fuel from fuel tanks.
Fuel Filter, In-Tank
An in-tank fuel filter is located on the inlet of the venturi pump. The inlet of the venturi pump has a nylon filter on it to prevent dirt and other particulate matter from entering the system. Water in the fuel tank can pass through the filter without restriction.
Fuel Filter, Fuel Injector Screen
An injector filter is located at the top of each injector and is not serviceable. If injector screen becomes clogged, replace the complete injector assembly. Refer to Section 03-04A, Section 03-04B and Section 03-04C for fuel injector information.
