Detailed Description

Carter M6750 is a mechanical replacement fuel pump for vehicles that rely on engine-driven fuel delivery. Its hose inlet, threaded outlet, and 1/2-20 UNF-2B outlet fitting support straightforward connection to the fuel system, while the specified pressure range of 6.5 to 7.5 helps maintain consistent fuel supply for carbureted operation. The included gasket or seal adds a needed sealing component for service work on Ford LTD, Mercury Grand Marquis, and Lincoln applications, as well as other listed models.

Common Issues This Pump Can Address

• Low fuel pressure at the carburetor
• Fuel starvation during acceleration or sustained driving
• Hard starting caused by weak mechanical fuel delivery
• Fuel leakage at the pump mounting interface when the seal is worn
• Inconsistent fuel flow from an aging engine-mounted pump

Installation Notes and Tips

Verify the inlet and outlet style before installation, since this pump uses a hose inlet and threaded outlet. Confirm the outlet thread size matches 1/2-20 UNF-2B and compare the vehicle’s fuel system layout, especially on 1980 Lincoln Continental and 1980 Lincoln Mark VI early-production vehicles without a return line, plus 1981 Mercury Marquis California emissions applications. Clean the mounting surface thoroughly and inspect fuel lines, clamps, and the carburetor inlet for wear before final assembly.

Quality Assurance

Carter Fuel Systems emphasizes premium OE fit, form, and function with broad vehicle coverage and problem-solving design features. The M6750 follows that approach for direct-replacement service on listed Ford, Lincoln, and Mercury models.
