SBC Mech. Street F/P

The Carter SBC Mechanical Street Fuel Pump (M6900) is a mechanical fuel pump engineered for small-block Chevrolet street and performance engine applications. This aluminum-bodied pump delivers 40 gallons per hour (GPH) at regulated pressure between 5.5–6.5 PSI, making it suitable for carbureted small-block Chevy engines requiring consistent fuel supply without electronic complexity. The mechanical design offers straightforward installation and maintenance for builders prioritizing reliability in naturally aspirated or supercharged street configurations.

The pump features 1/4-inch NPT female inlet and outlet ports, standard on most small-block fuel system plumbing. At 40 GPH output and 5.5–6.5 PSI regulation, the unit is calibrated for carbureted engines up to approximately 400–500 HP; higher displacement or forced-induction builds may require secondary fuel supply verification. The natural finish aluminum construction resists corrosion in typical engine bay environments while remaining lightweight compared to cast-iron alternatives. Installation requires basic mechanical skill and compatibility with existing fuel line diameter and carburetor inlet specifications.

This mechanical fuel pump is the standard choice for small-block Chevy street rods, restorations, and carbureted performance builds where electronic fuel injection is not desired. Engine builders, restoration shops, and enthusiasts working on naturally aspirated or moderately boosted small-block platforms rely on this pump's proven flow rate and pressure regulation. The 1.8-pound unit integrates into compact engine bays without additional electrical infrastructure, simplifying wiring and reducing parasitic load compared to electric fuel pump systems.
