Whether you have angled or flat Holley carburetor vent tubes, there should always be no less than 3⁄8-inch clearance (and preferably 1 inch of clearance) between the top of the vent tubes and the underside of the air cleaner lid. Tighter clearances place the lid too close to the tubes, resulting in incorrect float bowl reference pressures. A pressurized float bowl will cause an overrich condition.Force Fed Combinations from Holley… Early Action Photo Gallery from the 2016 Holley… First Look Gallery: Tech At Drag Week 2016Concept II SYNTHAMAX® Non-Oiled Round Air Filter Assemblies Concept II Round Air Filter Assemblies feature a beautiful lightweight aluminum lid.
