Billet By-Pass Regulator w/Return

The Quick Fuel Technology Billet By-Pass Regulator with Return (Model 30-1900QFT) is a precision fuel pressure regulator designed for high-performance fuel systems. It is ideal for custom engine builders, hot rod enthusiasts, and performance tuners who require reliable fuel pressure management in various applications, from street cars to racing platforms.

Constructed from durable aluminum with a red and clear anodized finish, this in-line regulator operates within a pressure range of 4.5 to 9 psi. Its bypass design allows for stable fuel pressure and includes dedicated return lines to prevent overpressurization. The regulator features 8 AN female O-ring connections for leak-free coupling and a 1/8-inch NPT gauge port for real-time pressure monitoring.

This regulator is particularly beneficial for those tuning fuel delivery curves during development or diagnostics. Its adjustable pressure range accommodates both gravity-feed and low-volume mechanical pump systems, making it a versatile choice for various fuel types, including gasoline, E85, and methanol blends.
