Carter Billet Racing Mechanical Fuel Pumps are the state-of-the-art in circle track and drag racing applications. These pumps are machined from 6061-T6 aluminum on CNC machines, assuring exact dimensions on every one. They utilize a 3-valve design providing simplified operation and high flow characteristics. The reinforced diaphragms are actuated by heat-treated, channeled levers. The fuel inlet and outlet feature No. 8 and No. 10 AN fittings that incorporate a coppercrush washer and are sealed with loctite. The fittings are plated steel and match up perfectly with today's braided stainless steel fuel lines. Each pump has a blue anodized finish accented with black oxide TORX self tapping screws.
