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 regulator engineered for carbureted and fuel-injected engines running gasoline, E85, or diesel fuel. This in-line regulator delivers stable fuel pressure across a wide operating range, making it ideal for both street and performance applications where consistent fuel delivery is critical to engine reliability and tuning accuracy.

The 30 to 120 psi pressure range accommodates a broad spectrum of fuel system configurations, from mild carbureted setups to aggressive turbocharged EFI platforms. The .500-inch valve orifice provides responsive regulation without excessive lag, while the dual outlet design—10 AN female O-ring inlet and 8 AN female O-ring outlet—ensures compatibility with modern fuel system components. The included 1/8-inch NPT port allows integration of external fuel pressure gauges or auxiliary sensors for real-time monitoring. At 1.9 lbs, this regulator adds minimal weight while maintaining the durability demanded by high-performance fuel systems.

This regulator suits street rods, custom classics, late-model EFI conversions, and modified engines where fuel pressure stability directly impacts idle quality, throttle response, and overall drivability. It's equally at home in professional tuning shops where dial-in consistency matters. The broad fuel compatibility—gasoline, E85 ethanol blends, and diesel—makes it a versatile choice for builders and restorers working with alternative fuels or multi-fuel engines. Aeromotive's reputation for precision engineering and component reliability ensures long-term performance in demanding automotive applications.
