Holley Fuel Pressure Regulator & Liquid Filled Gauge Kit 4.5-9PSI

Holley's adjustable fuel pressure regulators can be used to regulate fuel pressure for various types of carburetors. These regulators can be adjusted from 4-1/2 to 9 PSI. The fuel pump regulator works well with Holley's high-performance fuel pumps. For high-flow applications, use one fuel regulator per fuel bowl.

This fuel pressure regulator features a 3/8" NPT gauge port, and requires a reducer (617-6157) to install a fuel pressure gauge. The high-quality, liquid-filled stainless steel fuel pressure gauge is designed for remote mounting. It has a 0-15 psi range and a 1-3/4" face, with a 1/8" NPT connection.

The adjustable nature of these fuel pressure regulators allows users to set the desired fuel pressure, ranging from 4-1/2 to 9 PSI, to precisely meet the requirements of their carbureted applications. The integrated 3/8" NPT gauge port simplifies the installation of a fuel pressure gauge, enabling users to monitor the pressure in the fuel system.

Holley's high-performance fuel pump regulators are designed to work seamlessly with the company's line of high-flow fuel pumps. This combination ensures that the fuel delivery system is optimized for maximum performance, providing the necessary fuel pressure and flow to support the engine's demands.

For applications that require precise fuel pressure monitoring, the included liquid-filled stainless steel gauge is a valuable addition. The 0-15 psi range is well-suited for carbureted engines, allowing users to keep a close eye on the fuel pressure and make any necessary adjustments to maintain optimal engine performance.

Overall, these Holley fuel pressure regulators and gauges offer a comprehensive solution for tuning and monitoring the fuel system in carbureted applications.
