Keep clean fuel flowing to your pump with the Agility Auto Parts Fuel Pump Strainer, MPN 4050218. Mounted on the fuel pump inlet inside the tank, this strainer (often called a fuel pump sock) draws fuel through a fine mesh to catch rust, dirt, and sediment before they reach the pump and injectors. It's a direct-fit replacement for the 1988-1994 Ford Tempo, 1988-1993 Mercury Topaz, 1993-1997 Ford Probe, 1993-2002 Mazda 626, 1993-1997 Mazda MX-6, and 1994-1995 Acura Integra — see the "Vehicles it fits" section for engine-level fitment.
- Protects the fuel system: screens contaminants at the pump inlet so debris doesn't pass downstream.
- Durable materials: engineered from durable materials to meet or exceed OEM specifications.
- Broad coverage: part of Agility's complete line of fuel strainers spanning a wide variety of North American vehicle applications.
- North American logistics: stocked from distribution warehouses in Canada and the United States for timely delivery.
Signs the original strainer may need replacing include restricted fuel flow, hard starting, hesitation, or a whining fuel pump caused by a clogged inlet screen. If a plugged strainer is the cause, replacing it restores normal draw to the pump.
