12-804 Low Fuel Pressure Regulator Gauge for Carburetor Carb Quick Fuel

The 12-804 low fuel pressure regulator gauge assembly mounts between the fuel pump and carburetor to hold steady fuel pressure for consistent air-fuel delivery.

Overview

This 12-804 low fuel pressure regulator gauge fits inline on carbureted fuel systems to stabilize pressure reaching the carb, preventing flooding and fuel starvation. The built-in gauge lets you dial in a repeatable setting for Quick Fuel and other carburetor setups. It suits carb tuners, bracket racers, and classic engine rebuilders.

Good To Know

Q: Does this regulator include the pressure gauge? A: Yes, the gauge is built into the 12-804 regulator assembly so you can read pressure at the unit. Verify your fuel line thread sizes before installing.

Q: Can I use this on a stock mechanical fuel pump? A: It is intended for low pressure carbureted systems, which includes most mechanical pump setups feeding a carb. Confirm your target pressure falls within the regulator's adjustment range.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
