Sniper Billet EFI Fuel Regulator w/6an ORB Port

The Holley Sniper Billet EFI Fuel Regulator with 6AN ORB Port (part number 19-392) is a precision fuel pressure control component engineered for high-performance EFI fuel systems. Built from billet aluminum and finished in black anodize, this regulator maintains stable fuel pressure across a 40 to 130 psi operating range, making it compatible with gasoline, E85, and methanol fuel blends commonly used in modified and performance vehicles.

The regulator features three 6 AN female O-ring boss (ORB) ports for inlet, outlet, and return line connections, plus a 1/8 inch NPT port for boost reference or vacuum line integration. This configuration allows tuners and builders to plumb the unit into custom fuel rails and distribution systems without adapter complexity. The bypass design prevents excessive system pressure and fuel return during idle and cruise conditions, protecting injectors and fuel lines from overpressurization while optimizing fuel economy and engine efficiency across the RPM range.

Built for street machines, race applications, and fuel-injected engine conversions, the Sniper regulator suits builders and tuners who demand direct control over fuel delivery pressure. Its compact footprint (4.4 × 3.4 × 4.75 inches) fits tight engine compartments and custom fuel system layouts. The billet construction and anodized finish resist corrosion and thermal stress, essential for sustained performance in high-heat and high-boost environments where consistency in fuel management directly impacts ignition timing, air-fuel ratio stability, and overall drivetrain reliability.
