Screen dirt and debris out of the fuel before it reaches your pump with the Autobest Fuel Pump Strainer F321S. It fits many vehicles, among them the 1997-2004 Jeep Grand Cherokee, 1997-2004 Jeep Wrangler and 1997-2001 Jeep Cherokee — see the "Vehicles it fits" section for the full list and engine-level details. This push-fit strainer attaches at the pump inlet, drawing fuel through its filter media so contaminants are trapped before they can enter the pump.
If a clogged or torn original strainer is starving your pump and causing fuel-delivery problems, this replaces it. Diagnose the cause before replacing.
