Large 2-Port EFI Regulator

The Large 2-Port EFI Regulator from MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS is engineered for serious fuel system builders and performance mechanics working with electronic fuel injection platforms requiring dual fuel rail management or staged injection control. This regulator serves as the critical backbone of high-demand fuel delivery systems, whether you're tuning a carbureted-to-EFI conversion, managing twin fuel pumps on a modified engine, or implementing complex fuel mapping on a race platform. Built by Magnafuel—a trusted name among drag racers, street performance builders, and restoration shops—this component ensures precise pressure regulation across multiple fuel circuits simultaneously.

The 2-port design allows independent regulation of two separate fuel circuits, critical for applications like fuel rail isolation, bypass feed separation, or dual-injector-set operation on turbocharged and supercharged platforms. Large displacement engines and high-flow fuel system architectures demand a regulator with ample flow capacity and stable pressure response under load transients—precisely where this Magnafuel regulator excels. The unit's compact footprint (5.3 x 3.2 x 6 inches) and lightweight construction (1.05 lbs) make it ideal for engine bay integration on space-constrained builds, while maintaining the robust internal porting and adjustability that professional tuners and fabricators demand.

Performance builders, EFI conversion specialists, and tuning shops benefit most from this regulator on LS swaps, small-block modifications, and custom fuel system fabrications where OEM fuel management is replaced entirely. It integrates seamlessly into custom fuel rails, surge tank setups, and modular fuel systems using -6 or -8 AN inlet/outlet ports (standard Magnafuel architecture). Installation pairs well with quality fuel pump controllers and pressure gauges for real-time diagnostics; proper line sizing and damping ensure stable readings and consistent injector pulse. Whether you're building a street machine, street-strip hybrid, or dedicated race platform, the Large 2-Port EFI Regulator from MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS delivers the regulation precision and durability that separates amateur builds from professional results.
