The Caterpillar 3044C and C3.4 are 4-cylinder diesel engines powering Cat's popular compact track loaders and skid steer loaders — some of the most widely used compact construction machines in the world. These engines use a common rail high-pressure fuel pump to pressurize fuel for the injection system, delivering precise fuel metering for clean combustion and reliable performance. When the high-pressure pump fails, fuel rail pressure drops — causing hard starts, rough running, power loss, excessive black smoke, or a complete no-start condition. This brand-new aftermarket high-pressure fuel pump is a direct replacement covering 17 cross-reference formats across Cat OEM, Denso, Mitsubishi, and Bosch part numbers, including Cat 336-9190 and Denso 104642-3050.
