Airtex FS197 Fuel Pump Strainer - Front

Fuel Pump Strainer for Ford E-Series Applications

Airtex FS197 is an internal fuel pump strainer built to filter fuel before it reaches the pump and downstream fuel system components. It uses gradient-density media to capture contaminants at the tank pickup point, helping maintain fuel flow in Ford E-150, E-250, E-350 Super Duty, Expedition, and select Mercury Villager and Nissan Quest applications.

Key Features

• Airtex FS197 fuel pump strainer with gradient-density media
• Internal, push-on attachment type with a specific-fit design
• White strainer material with 180.3 mm length and 53.3 mm width

• Built as the first filtration stage before the fuel pump and fuel filter
• Cross-references Airtex F274S for the same application

Detailed Description

This Airtex fuel pump strainer is made for vehicles that use an internal pickup-side filter at the fuel pump module. The FS197 helps trap debris before it can circulate through the fuel system, supporting cleaner fuel delivery and reducing strain on the pump and filter. It is a specific-fit replacement for select Ford E-150 Econoline, Ford E-250 Econoline, Ford E-350 Econoline, Ford E-150 Club Wagon, Ford E-350 Club Wagon, Ford Expedition, Mercury Villager, and Nissan Quest applications. This part number, FS197, is also listed with common interchange references used in fuel system service.

What It Helps Address

• Fuel contamination entering the pump pickup area
• Restricted fuel flow caused by debris at the strainer
• Premature wear on the fuel pump from unfiltered particles
• Reduced fuel filter life from excessive inlet contamination
• Poor fuel delivery caused by a clogged tank-side screen

Installation Notes and Tips

Install the strainer on the internal fuel pump pickup using the push-on attachment style and verify the 11.0 mm fitting size before assembly. Because this is a specific-fit component, confirm the vehicle year, make, model, and position against the listed applications before service. For Ford E-150 Econoline, Ford E-250 Econoline, and Ford E-350 Super Duty fuel system repair, replacing the strainer during pump service helps restore proper inlet filtration.

Quality Assurance

Airtex positions this strainer as a gradient-density filtration component for fuel system protection. The manufacturer notes that a new strainer is required to validate the warranty, so replacing the strainer during fuel pump service is part of the approved service process.
