APR MS100077 Direct Injection Fuel Pump

The APR MS100077 Direct Injection Fuel Pump is engineered for high-performance applications, specifically designed to meet the demanding fuel delivery requirements of the Audi 80 (1988) and Audi S5 (2008-2012). Operating at a maximum pressure of 1973 PSI (136 bar), this pump ensures precise fuel atomization directly into the engine cylinders, optimizing combustion efficiency and power output.

Unlike traditional multi-port injection systems that typically function at lower pressures (40-60 PSI), the MS100077 leverages a dual-lobe cam system to drive two cam-driven high-pressure fuel pumps. This innovative design allows for increased fuel displacement as engine RPM rises, enhancing overall engine performance. The pump's internal capacity is critical, as it is designed to maintain a steady fuel supply even under high-demand scenarios, such as those encountered with the stage III+ TVS1740 supercharger system.
