      Engine-Powered Fuel Pump. Revitalize the fuel pressure in your vehicle and help your engine run smoother by installing this Wrangler mechanical fuel pump on your ride. This pump uses the motion of your engine to pump fuel to the engine and power its movements. This pump works on Jeep CJ5 and CJ7 models as well as select Wrangler YJ vehicles.

      On-Engine Mount Design. This pump mounts on top of the engine itself and relies on a cam to move its lever up and down to create suction to move the fuel to the engine. This pump utilizes a simple bolt-on mount design for simple installation.

      Built From Rugged Materials. This fuel pump is crafted from a blend of aluminum and plastic and is designed to last for years. The pump resists corrosion and is made to handle exposure to the elements.

      Medium Installation Requirements. This fuel pump is moderately difficult to install and requires 30-40 minutes for a mechanic to install it. This device sits on the engine and uses the motion of the engine to supply fuel to the rest of the vehicle.

      12-Month Warranty. This mechanical fuel pump is covered by a 12-month warranty. This warranty covers defects, material issues, and workmanship problems.

      Application. This replacement fuel pump works with 1977-1990 Jeep CJ5, CJ7, and select Wrangler YJ models with rear inlet fittings. The pump must be paired with 4.2L engines and doesn’t require modifications to function.
