Detailed Product Overview

Built as the first filtration point in the fuel delivery system, the Airtex FS233 fuel pump strainer helps capture debris before it can circulate through the pump and downstream components. This part cross-references Delphi FS0199 for the same application.

What It Helps Address

• Fuel pump inlet contamination from tank debris
• Restricted fuel flow caused by a clogged strainer
• Premature wear on the fuel pump from dirty fuel
• Reduced fuel system cleanliness after tank service
• Fuel delivery issues related to degraded filtration at the pump inlet

Installation Notes and Tips

Install the strainer on the in-tank fuel pump using the push-on connection and verify the 11.95 mm fitting inside diameter before assembly. Because this is a specific-fit part, confirm the vehicle year, make, model, and position against the fitment list before service. Airtex notes that a new strainer is required to validate the warranty on the fuel pump assembly.

Quality Assurance

Airtex positions this strainer as a reliable filtration component for fuel system service. The gradient-density media is intended to provide maximum filtration at the pump inlet, helping extend the service life of the fuel pump, fuel filter, and fuel system components.
