Fuel Pressure Regulator - 160GPH

The Fuel Pressure Regulator - 160GPH (SKU EDE1727) is an essential tuning component for any fuel system upgrade, street performance build, or ethanol-compatible engine modification. Whether you're running E85, pump gas, or methanol, this in-line regulator maintains precise fuel pressure between 5 to 10 psi, protecting your injectors and carburetor from dangerous pressure spikes while ensuring consistent atomization across the RPM range. This regulator is ideal for carbureted engines, nitrous systems, forced induction setups, and fuel-injected platforms requiring aftermarket fuel delivery control.

Built from aluminum with black and clear anodized finish, this regulator combines durability with visual appeal in any engine bay. The in-line design features 3/8 inch NPT inlet and outlet ports for seamless integration into existing fuel lines, plus a dedicated 1/8 inch NPT port for vacuum reference or gauge monitoring—critical for dial-in and real-time pressure diagnostics. The 160GPH flow capacity handles high-volume fuel systems without restriction, while the compact 3.8 x 3.1 x 4.7 inch footprint fits tight spaces on custom fuel rails. Its multi-fuel compatibility (E85, gasoline, and methanol) makes it a versatile choice for flex-fuel and alternative-fuel enthusiasts.

Mechanics and tuners favor this regulator for carburetor rebuild projects, turbo/supercharger upgrades, and standalone ECU tuning where OEM fuel pressure curves fall short. The adjustable 5–10 psi range accommodates both low-impedance and high-impedance injectors, allowing fine pressure tuning to match your specific fuel map and atomization goals. Installation requires NPT-threaded fuel line fittings and basic mechanical aptitude; vacuum reference lines should connect to ported engine vacuum for load-dependent pressure compensation. Weighing just 0.9 lbs, it's an affordable, proven solution for fuel system reliability and performance consistency.
