Standard 2-Port EFI Regulator

The Standard 2-Port EFI Regulator by MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS is engineered for builders and enthusiasts running electronic fuel injection setups who demand reliable fuel pressure management. This compact regulator sits at the heart of any modern EFI conversion or performance fuel system, maintaining consistent fuel delivery under varying engine loads and RPM ranges. Whether you're upgrading a classic carbureted engine to EFI or fine-tuning a high-horsepower street or track build, this two-port design provides the pressure stability necessary for precise fuel metering and optimal combustion efficiency.

The dual-port configuration allows independent regulation of fuel supply and return lines, a critical feature in systems requiring bypass flow management and heat dissipation. By separating high-pressure delivery from low-pressure return, the regulator minimizes fuel temperature rise in the tank and rails—a common issue in high-output applications where fuel velocity generates heat. The internal bypass valve maintains set pressure across throttle transitions, preventing stumble and ensuring smooth idle-to-boost transitions. MAGNAFUEL's proven design uses precision-machined internals and spring-loaded diaphragms to hold tolerance across climatic extremes, making it suitable for everything from street cars to bracket racing applications.

This regulator is ideal for fuel-injected engine swaps, turbocharged platforms, and standalone EFI systems where OEM regulators fall short of flow or reliability demands. Mechanics and tuners rely on MAGNAFUEL regulators for their repeatability—consistent pressure regulation translates directly to repeatable tune files and predictable drivability. Installation requires standard -6 or -8 AN fittings (typical in performance fuel systems) and mounts to any accessible engine bay location. The compact 5.3 x 3.2 x 6-inch footprint and 0.9-pound weight make packaging straightforward in tight engine bays, while the rugged construction ensures years of trouble-free service in both naturally aspirated and forced-induction applications.
