## Description

Proper power valve selection is crucial to carburetor tuning Demon Fuel systems offers a complete range of quality power valves to accommodate every tuning requirement. Our power valves are rated in inches of mercury required to open the valve. Most 4150/4160/2300 model carburetors use the standard while 4500 and alcohol carburetors use the Hi-Flow power valve. Power valves should be replaced periodically to prevent leakage. All include gasket.
