Carter M6676 Mechanical Fuel Pump

Carter M6676 Mechanical Fuel Pump

The Carter M6676 is a mechanical fuel pump built for OE-style fit, form, and function on select Ford truck applications. It supports steady fuel delivery with hose-style inlet and outlet connections, making it a direct replacement choice for classic Ford F-100, F-150, F-250, and F-350 models from the mid-1970s.

Key Features

• Mechanical fuel pump for air and fuel delivery systems
• Hose inlet and hose outlet connections
• 1 inlet and 1 outlet with 9.5 mm outside diameter ports
• Minimum flow rating of 34
• Operating pressure range: 5.5 to 7.5
• Gasket or seal included
• 2 mounting holes for OE-style installation
• Cross-reference part numbers include Airtex 6676 and Delphi MF0076

Detailed Description

Carter M6676 is a mechanical fuel pump engineered for vehicles that use a cam-driven fuel supply system. It is compatible with 1974 Ford F-100, 1974 Ford F-250, 1974-1976 Ford F-350, and 1975-1976 Ford F-100, F-150, and F-250 models, including in-cab tank applications where noted. The pump’s hose-style inlet and outlet, 9.5 mm port diameters, and included gasket or seal support a straightforward replacement on the correct Ford truck fuel system. This part cross-references Airtex Fuel Pumps 6676 and Delphi MF0076 for the same application.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under normal engine operation
• Low fuel pressure in a mechanical pump system
• Inconsistent fuel flow to the carburetor
• Replacement needs on aging Ford truck fuel systems

Installation Notes and Tips

Verify the vehicle’s fuel system layout before installation, especially on 1975-1976 Ford F-100, F-150, and F-250 models with in-cab tank configurations. Confirm hose size, port orientation, and mounting-hole alignment against the original pump. Use the included gasket or seal during installation and inspect fuel lines for wear, cracking, or contamination before placing the vehicle back in service.

Quality Assurance

Carter Fuel Systems focuses on OE fit, form, and function with broad vehicle coverage and problem-solving design features. The M6676 follows that approach for classic Ford truck applications and is built as a mechanical replacement fuel pump for the specified fitment.
