Belt Drive EFI Regulator 30-120 psi .500 Valve

The Aeromotive Belt Drive EFI Regulator 30-120 psi with .500 valve is a precision fuel pressure management component designed for both carbureted and EFI engine builds that require external belt-driven mechanical regulation. This regulator is essential for achieving stable and adjustable fuel delivery in performance and custom engine configurations, providing more control than traditional in-tank regulators. Whether you're working on a naturally aspirated stroker, a turbocharged swap, or a fuel-injected hot rod, this regulator allows for precise fuel pressure tuning across the 30–120 psi operating range.

The belt drive design eliminates the need for engine vacuum or electric pump circuits, delivering mechanical regulation that scales with engine speed via a serpentine belt coupling. This design prioritizes damping and response stability, which is critical for tuning carburetors sensitive to pressure fluctuations or for feeding fuel-injected systems that require consistent rail pressure. The regulator's internal components are engineered to ensure reliable performance under load.

Ideal for engine builders and performance enthusiasts, this regulator is particularly beneficial for dedicated track cars and drag racing applications. Its compact footprint and lightweight construction make installation flexible in engine bays where space is limited. With its robust design, the Aeromotive Belt Drive EFI Regulator is a reliable choice for those looking to enhance their engine's fuel delivery system.
