The Hydraulically actuated Electronically controlled Unit Injectors (HEUI) use a hydraulic pump and engine oil to generate fuel injection pressure, and an ECM to control the pressure and amount of fuel injected into the cylinders. The operation of the HEUI fuel system is completely different from any other type of fuel system that is actuated mechanically. The HEUI fuel system is completely free of adjustment.

EPU Invests numerous hours into the development and testing of C7 and C9 HEUI Fuel Pumps. Buy quality Caterpillar parts today at the best prices in SA.
