HP (high-pressure) cock

 
McGraw-Hill Dictionary of Aviation:

HP (high-pressure) cock

Home > Library > Cars & Vehicles > Aviation Dictionary
The cock(s) used to stop the engine by cutting off the fuel supply to the burners. These may be electrically or manually controlled and are usually incorporated into fuel control units to eliminate unnecessary pipe connections. Unlike the low-pressure (LP) cock, which cuts off fuel supply from the aircraft fuel system, the HP cock cuts off fuel supply from the HP pump(s).
