Detailed Product Overview

Built for classic Jeep fuel system service, the Carter M6505 supports direct mechanical pump replacement on 1972-1975 Jeep CJ5 and Wagoneer, plus 1974-1975 Jeep Cherokee, J10, and J20 applications. The threaded ports and OE-style mechanical layout make it a practical choice when replacing a worn pump that is causing fuel delivery inconsistency. This part cross-references Airtex Fuel Pumps 6505 and Delphi MF0042 for the same application.

Common Fuel System Issues It Can Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under load or at higher engine demand
• Low fuel pressure from a worn mechanical pump
• Intermittent stalling related to inconsistent pump output
• Fuel seepage at the pump-to-line connection when the original unit is deteriorated

Installation Notes and Tips

Confirm the vehicle’s fuel line thread size and pump orientation before installation. Because this pump uses threaded inlet and outlet connections, clean the mating surfaces and inspect the fuel lines for wear or damaged threads. Replace the gasket or seal during service and verify fuel pressure after installation to confirm the system is operating within specification.

Quality Assurance

Carter Fuel Systems focuses on OE fit, form, and function with broad vehicle coverage and problem-solving fuel system components. The M6505 follows that approach for classic Jeep fuel pump replacement service.
