Delphi FS0004 Fuel Pump Strainer

Fuel Pump Strainer for OE-Style Filtration

The Delphi FS0004 fuel pump strainer is a standard replacement part built for fuel system filtration at the pump inlet. It uses a 60 micron Saran strainer media with a push-on attachment and a 19.0 mm inside diameter fitting for direct service on listed applications.

Backed by Delphi’s OE heritage and decades of supplier experience, this fuel pump strainer is made for drivers servicing older Ford, Chevrolet, Pontiac, and Mercury fuel systems that require a reliable inlet screen during pump replacement.

What It Helps Address

• Fuel pump inlet contamination from debris in the tank
• Restricted fuel flow caused by a clogged strainer
• Premature pump wear related to dirty fuel pickup conditions
• Service issues during fuel pump replacement on older Ford, Chevrolet, Pontiac, and Mercury vehicles
• Repeat failures caused by contamination left in the fuel tank

Installation Notes and Tips

Before installing a new fuel pump strainer, clean the fuel tank to reduce the chance of debris entering the replacement pump. This is especially important on 1985-1986 Ford F-150 and F-250 models with 17 or 19 gallon midship tanks, 1988-1989 Ford F-350 with rear steel tank, and 1986 Mercury Marquis with extended range fuel tanks. Delphi also notes fuel tank cleaning kit FC01 for these applications.

Verify the attachment style and fitting size against the original part before installation. Use the included instruction sheet and confirm the fuel system is clean before returning the vehicle to service.

Quality Assurance

Delphi builds aftermarket parts using knowledge developed through long-term OE supply experience. The FS0004 is a standard replacement fuel pump strainer intended for listed vehicle applications and fuel system service where inlet filtration is required.
