Detailed Description

Sparta PN8035 mechanical fuel pump is built for older Ford and Mercury fuel systems that rely on engine-driven fuel delivery. It is a gas-only pump with a threaded inlet and outlet, making it a practical replacement for service work on classic trucks and passenger cars. The aluminum housing and standard replacement design support routine maintenance on vehicles where original-style mechanical fuel pump service is required.

This part cross-references Carter M3528 and Airtex 6523 for the same application. It is a direct-fit style option for 1956-1969 Ford F-100, F-250, and F-350 models, as well as select Mercury applications including the 1960-1966 Colony Park and 1962-1964 Thunderbird.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under normal driving conditions
• Low fuel pressure in mechanical pump systems
• Fuel system service on aging classic vehicles
• Replacement of worn or leaking original-style pumps

Installation Notes and Tips

Verify the threaded inlet and outlet orientation before installation and confirm the 2-hole mounting pattern matches the engine application. Replace the gasket or seal during service, and follow the included instruction sheet for proper setup. Confirm fuel pressure requirements and line routing before returning the vehicle to service.
