Carter M6626 Mechanical Fuel Pump

Carter M6626 Mechanical Fuel Pump

The Carter M6626 is a mechanical fuel pump built for OE-style fit, form, and function on a wide range of classic Chevrolet and GMC applications. It uses a hose-style inlet, threaded outlet, and a short-housing configuration for 3-line fuel systems found on many C10, C20, Camaro, El Camino, and P30 models.

Key Features

• Mechanical fuel pump for carbureted fuel delivery systems
• Hose inlet with 9.5 mm outside diameter
• Threaded outlet with 5/8-18 UNF-2B fitting
• Gasket or seal included for installation
• 2 mounting holes for OE-style attachment
• Operating pressure range: 7.5 to 9 psi
• Minimum flow rating: 40
• Compatible with short housing, 3-line fuel pump applications

Detailed Description

Carter M6626 is engineered for vehicles that rely on a mechanical fuel pump mounted to the engine and driven by the camshaft. The short-housing design and 3-line configuration make it a direct-match solution for many older Chevrolet and GMC trucks, vans, and passenger cars, including 1976-1986 Chevrolet C10, 1982-1987 Chevrolet Camaro, 1971-1976 Chevrolet El Camino, and 1980-1987 Chevrolet P20 applications. This part number, M6626, also cross-references Airtex 41216 for the same application.

The Carter Fuel Systems program focuses on OE fit and vehicle coverage, and this pump follows that approach with the correct inlet and outlet layout for the listed applications. It is a practical replacement for worn pumps that no longer maintain steady fuel delivery or proper pressure in carbureted systems.

What It Helps Solve

• Hard starting caused by weak or inconsistent fuel delivery
• Fuel starvation under load or at higher engine demand
• Low fuel pressure in carbureted Chevrolet and GMC engines
• Stalling from a failing mechanical pump diaphragm or check valves
• Fuel system issues on short-housing, 3-line pump setups

Installation Notes and Tips

Verify the vehicle uses a short housing mechanical fuel pump with a 3-line configuration before ordering. Confirm the outlet thread size, inlet style, and mounting-hole layout against the original pump. The gasket or seal is included; mounting hardware is not included. Clean the mounting surface and inspect the fuel lines before installation to help ensure proper sealing and fuel delivery.

Quality Assurance

Carter positions this fuel pump line around OE fit, form, and function with broad coverage for classic applications. The M6626 is built for direct replacement use on the listed Chevrolet and GMC vehicles, including C10, C20, Camaro, El Camino, and related models.
