Detailed Description

Airtex FS131 is a fuel pump strainer built to serve as the first filtration stage in the fuel delivery system. By filtering debris before it reaches the pump, this strainer helps support cleaner fuel flow and reduces the chance of contamination moving deeper into the fuel system. It is an internal, push-on style component made for specific-fit applications, including 1999 Mitsubishi 3000GT, 1991-1996 Dodge Stealth, 1994-1995 Toyota MR2, 1992-1994 Mitsubishi Eclipse, 1990 Mitsubishi Eclipse, 1990-1994 Plymouth Laser, 1991 Mitsubishi Eclipse to 01/1991, 1988-1991 Toyota Camry with OE Style Pump, 1988-1991 Toyota Corolla with OE Style Pump, 1989-1990 Mitsubishi Sigma, and 1988 Mitsubishi Galant. This part cross-references Bosch 68029 and Carter STS-36 for the same application. The Airtex FS131 is a practical choice when replacing a worn or contaminated fuel pump strainer on vehicles such as the Mitsubishi Eclipse, Toyota Camry, and Dodge Stealth.

Common Problems It Can Help Address

• Fuel pump inlet contamination from tank debris
• Restricted fuel flow caused by a clogged strainer
• Premature wear on the fuel pump from abrasive particles
• Reduced fuel system cleanliness after pump service
• Loss of filtration performance from an aged or damaged strainer

Installation Notes and Tips

Install the strainer on the fuel pump inlet using the push-on attachment style. Confirm the vehicle uses the listed specific-fit application before ordering, and match the OE-style pump requirement where noted for Toyota Camry and Toyota Corolla applications. Because this is an internal fuel system component, clean the surrounding area before installation to help prevent new contamination from entering the tank or pump assembly.

Quality Assurance

Airtex positions this strainer as a replacement filtration component for fuel system service, with gradient density media used to support reliable contaminant capture. A new strainer is required to validate the warranty.
