This fuel pump strainer supports cleaner fuel delivery by capturing contaminants before they enter the pump assembly. This part cross-references Airtex FS243 and Carter STS-262 for the same application. Part number F344S is also listed under interchange references used across multiple OE-style fuel system applications.

What It Helps Address

  • Sediment entering the fuel pump inlet
  • Restricted fuel flow from debris buildup
  • Premature wear caused by contaminated fuel
  • Fuel delivery issues related to a clogged strainer
  • Maintenance needs on aging in-tank fuel systems

Installation Notes

Verify vehicle fitment by year, make, model, and notes before installation. The push-fit strainer installs at the fuel pump inlet and should be matched to the correct pump assembly and tank configuration. Clean the surrounding fuel system components during service to reduce the chance of recontamination. Confirm the replacement part number F344S against the original strainer style before assembly.
