Airtex FS38 Fuel Pump Strainer

Fuel Pump Strainer for GM Applications

The Airtex FS38 fuel pump strainer is a specific-fit internal filter media designed to help keep fuel system contaminants away from the pump and downstream components. It is a practical replacement for service work on Buick, Oldsmobile, and Pontiac applications that use this style of in-tank strainer.

Key Features

• Airtex FS38 fuel pump strainer for internal fuel pump filtration
• Gradient-density media helps capture contaminants before they reach the fuel pump and fuel filter
• Specific-fit design for confirmed vehicle applications
• White strainer construction with a 169.0 length and 45.0 width
• 11.0 inside diameter fitting for proper pump connection
• No gasket included and no mounting hardware included

Detailed Description

Built for fuel delivery service, the Airtex FS38 is a fuel pump strainer that sits inside the tank and acts as the first stage of filtration. By trapping debris before it enters the pump, this strainer helps support cleaner fuel flow and can reduce strain on the fuel pump and fuel system over time. The FS38 is a specific-fit part for select GM vehicles, including 1993-1999 Buick LeSabre, 1993-1996 Buick Century, 1996 Buick Park Avenue, 1993-1999 Pontiac Bonneville, and related Oldsmobile applications.

This part cross-references Delphi FS0050 and Spectra Premium STR06 for the same application. If you are replacing a worn or contaminated strainer on a Buick LeSabre, Oldsmobile 88, or Pontiac Bonneville, the Airtex FS38 provides a direct service option with the correct internal fitment profile.

What It Helps Address

• Fuel pump inlet restriction caused by debris buildup
• Contamination entering the fuel pump from the tank
• Reduced fuel delivery from a clogged in-tank strainer
• Premature wear on the fuel pump and fuel filter
• Service issues tied to aged or damaged fuel pump filtration media

Installation Notes and Tips

Install the FS38 as an internal fuel pump strainer during fuel pump service or tank access repairs. Verify the pump inlet size and vehicle application before installation, and inspect the tank for sediment or contamination that could shorten the life of the new strainer. Because this is a specific-fit part, confirm the exact model year and fuel system configuration before ordering.

Quality Assurance

Airtex specifies that a new strainer is required to validate the warranty on the fuel pump assembly. The FS38 is built as a fuel system filtration component for select Buick, Oldsmobile, and Pontiac applications, with gradient-density media intended to provide reliable first-stage filtration.
