Airtex FS187 Fuel Pump Strainer

Airtex FS187 Fuel Pump Strainer

The Airtex FS187 fuel pump strainer is a specific-fit internal fuel pump filter media designed to help keep contaminants out of the fuel system. It serves as the first stage of filtration before fuel reaches the pump and downstream components, supporting cleaner fuel delivery in 1995-1999 Ford Contour, Mercury Mystique, and 1999 Mercury Cougar applications.

• Specific-fit internal fuel pump strainer for select Ford and Mercury vehicles
• Gradient density media helps capture fuel system contaminants at the pump inlet
• White strainer construction with 139.0 length and 90.0 width
• 11.0 inside diameter fitting for proper pump-side connection
• Fits 1995-1998 Ford Contour and 1995-1998 Mercury Mystique
• Fits 1999 Ford Contour, 1999 Mercury Cougar, and 1999 Mercury Mystique with listed date limits

Fuel System Filtration Details

Airtex FS187 is built as an internal fuel pump strainer for direct replacement in specific applications. The media element is positioned at the fuel pump inlet to help reduce abrasive debris entering the pump and fuel delivery path. This part cross-references Delphi FS0096 for the same application.

Common Issues Addressed

• Fuel pump inlet contamination from tank debris
• Restricted fuel flow caused by a clogged strainer
• Premature wear on the fuel pump from unfiltered particles
• Reduced fuel filter life due to excess contamination upstream
• Fuel delivery inconsistency in Ford Contour, Mercury Mystique, and Mercury Cougar applications

Installation Notes

Confirm the pump inlet size and vehicle build date before installation. This strainer is for internal mounting and does not include mounting hardware. Replace the old strainer during fuel pump service to maintain proper filtration at the inlet and to match the specified application for the Airtex FS187.

Quality Assurance

Airtex positions this strainer as a replacement fuel system filtration component for specific-fit applications. The manufacturer notes that a new strainer is required to validate the warranty, so the existing strainer should not be reused during service.
