Detailed Description

Sparta PN8009 is a mechanical fuel pump engineered for Jeep vehicles that rely on a cam-driven fuel delivery system. It uses a hose-bead inlet with a 0.313 outside diameter and a threaded outlet connection, making it suitable for service replacement on classic Jeep Wrangler, CJ5, CJ7, Cherokee, Scrambler, Wagoneer, J10, and J20 models. This part cross-references Airtex 6737 and Carter M6737 for the same application.

As a gasoline pump with a 5 to 7.0 pressure range and 20.0 average flow rating, PN8009 supports consistent fuel delivery for carbureted engines found in many earlier Jeep platforms. The included gasket and seal help complete the repair, while the aluminum housing supports long-term underhood use.

Common Repair Uses

• Hard starting caused by weak fuel delivery
• Fuel starvation during acceleration or load changes
• Low fuel pressure in carbureted Jeep engines
• Fuel leaks at an aging mechanical pump body or seal
• Restoration replacement for original Jeep fuel system components

Installation Notes and Tips

Verify inlet and outlet orientation before installation, and confirm the 1/2" - 20 threaded outlet connection matches the existing fuel line setup. Inspect the mounting surface, replace worn fuel lines as needed, and use the included gasket during assembly. Prime the fuel system and check for leaks after startup.
