The MSD Ignition HP Electric Fuel Pump (Model 2225) is a compact in-line electric fuel pump engineered for high-performance fuel delivery in marine, automotive, and powersports applications. Rated at 43 gallons per hour (GPH) at 40 pounds per square inch (PSI), this pump delivers consistent fuel pressure across a wide operating range, making it suitable for carbureted and fuel-injected engine platforms that demand reliable fuel supply during sustained operation or high-demand scenarios.
The pump features 3/8-inch hose barb inlet and 5/16-inch hose barb outlet ports, sized for standard fuel line compatibility and optimized flow transitions. The 43 GPH output capacity supports engines requiring moderate to high fuel volume without sacrificing pressure stability at 40 PSI—a critical parameter for preventing vapor lock and ensuring clean, dry fuel delivery to the carburetor or fuel rail. Weighing just 1.75 pounds and dimensioned at 3 x 2.9 x 9.4 inches, this pump integrates into tight engine compartments and custom fuel system layouts. Installation is simplified by included mounting brackets, eliminating the need for improvised fastening solutions.
Users building or restoring high-performance engines, marine power plants, and off-road vehicles benefit from the MSD 2225's compact form factor and industry-standard fuel delivery specifications. The pump is commonly selected for street-legal hot rods, race support vehicles, boat refueling systems, and vintage engine restorations where OEM fuel pump capacity is insufficient or unavailable. MSD Ignition's fuel pump line is known for supporting demanding duty cycles and marginal fuel conditions found in field operations and extended-use scenarios.
Electric in-line pumps of this specification are preferred over mechanical pumps in applications requiring consistent pressure regardless of engine RPM, cooler fuel delivery, and remote mounting capability. The 40 PSI rating sits at the optimal balance for carbureted engines and early fuel injection systems, reducing the likelihood of float bowl overflow or injector fouling while maintaining sufficient head pressure for reliable cold-start performance.
