Detailed Description

Airtex FS162 is a specific-fit fuel pump strainer designed to serve as the first filtration stage in the fuel delivery system. Its gradient density media is intended to help reduce the amount of debris reaching the fuel pump and downstream fuel filter, supporting cleaner fuel flow in vehicles that use an internal strainer design. This part number is used in select Hyundai XG350 and XG300 applications, as well as Subaru Legacy and Subaru Impreza models with the listed pump configurations.

For buyers searching for a fuel pump strainer for 2002-2003 Hyundai XG350, 2001 Hyundai XG300, or Subaru Legacy and Impreza fuel pump service, FS162 provides a direct replacement option with the correct internal fitment profile. The Airtex FS162 is also referenced by other aftermarket numbers, including Carter STS-115, 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 abrasive particles
• Reduced fuel filter service life from excess contamination
• Fuel delivery issues related to a deteriorated internal strainer

Installation Notes and Tips

Install the strainer on the fuel pump inlet using the push-on attachment style and verify the pump configuration before ordering. Fitment is specific, not universal. Confirm the vehicle application carefully for 2002-2003 Hyundai XG350, 2001 Hyundai XG300, 1999 Subaru Legacy with 1 inch diameter pump, 1990-1996 Subaru Legacy with 1 inch diameter pump, 1997 Subaru Impreza with offset mounting, and 1995-1996 Subaru Impreza. Replace the old strainer during fuel pump service to maintain proper filtration at the tank level.

Quality Assurance

Airtex positions this strainer as a replacement filtration component for fuel system service, with the manufacturer noting that a new strainer is required to validate the warranty. Use a new FS162 during fuel pump repair or replacement to keep the fuel system filtration path in proper service condition.
