Review HOLLEY Standard Main Metering Carburetor Alcohol Jet 5/16-32 Thread .138

The Holley 122-138 Standard Carburetor Alcohol Jet is a crucial component for any race or high-performance applications utilizing alcohol fuel. This jet is specifically designed for Holley 122, 141, 4150, and 4160 series carburetors, making it a versatile choice for a wide range of automotive applications.
