High-output EFI engines rely on steady, accurate fuel pressure to maintain a consistent tune in both street and racing conditions. As load and demand change, a properly designed regulator helps keep fuel delivery stable so your combination performs the way it was intended. The Holley HP Billet EFI Bypass Fuel Pressure Regulator is built to provide that level of control.
CNC-machined from 6061-T6 billet aluminum, this regulator is engineered for strength and long-term durability. The body features a black bright-dip anodized finish, complemented by a clear bright-dip anodized top for added corrosion resistance and a refined look. Pressure is adjustable from 15 to 65 PSI, making it suitable for a wide range of EFI setups that utilize a return-style fuel system. It is intended for use with electric fuel pumps only. Port configuration includes one -8 AN O-ring inlet, one -8 AN O-ring outlet, one -6 AN O-ring return, and a 1/8-inch NPT port for a pressure gauge.
Designed to work with Holley HP inline fuel pumps and other high-pressure electric pumps requiring a return line, the regulator also provides a manifold reference fitting for boost-referenced applications. A mounting bracket is supplied to support secure and straightforward installation. Backed by a 1-Year Limited Warranty.
