Big-time fuel flow for big-time performance. Carter Competition Series Race Super mechanical fuel pumps deliver big-time fuel flow. Their free-flow output is 172 gph. Despite this high capacity, their compact size means that they often fit where other high-performance pumps won't. In addition, they're ''clockable,'' which allows rotation of the inlet and outlet. They have heat-treated, high-speed levers, plus -10 AN inlets and -8 AN outlets, with fittings included. With 7 to 8.5 psi operating pressure, no regulator is required.
