Fuel Pump Mechanical Ford 351M / 351C / 400

The Carter Fuel Pump Mechanical Ford 351M / 351C / 400 (MPN M6882) is a carburetor-fed mechanical fuel pump engineered for classic Ford V8 engines spanning the 351 modified, 351 Cleveland, and 400 cubic inch platforms. This aluminum-bodied pump delivers 23 gallons per hour at a regulated 5.5–6.5 psi, meeting the fuel delivery demands of naturally aspirated Ford big-block powerplants. Carter's mechanical pump design operates directly off the engine's camshaft, requiring no electrical supply and offering direct mechanical reliability in applications where simplicity and proven performance matter.

The pump features a 3/8-inch hose barb inlet for fuel tank pickup and a 1/2–20 inverted flare female outlet for carburetor feed lines. The 23 gph flow rate is calibrated for stock and moderately modified carbureted engines; the 5.5–6.5 psi output range prevents fuel starvation under load while protecting carburetor floats from excessive pressure. Natural aluminum finish provides a classic underhood appearance. Weighing 1.35 pounds with compact overall dimensions (6.7 x 4.1 x 13 inches), this pump integrates cleanly into tight engine compartments typical of 1960s and 1970s Ford muscle and vintage vehicles.

Buyers restoring or maintaining original Ford 351M, 351C, and 400 engines choose this pump for direct fit compatibility and verified replacement capability. Enthusiasts rebuilding carbureted Ford drivetrains value mechanical pumps for their independence from electrical systems and their proven track record across decades of field use. The specified flow and pressure ratings ensure proper fuel delivery for cruise, acceleration, and extended driving without modification to existing fuel system plumbing. This is a core component for serious Ford engine builders and restoration professionals.
