Carter Competition Series Race Super mechanical fuel pumps deliver big-time fuel flow. Their free-flow output is 172 gph, and 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 the 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.
