The Caterpiillar Fuel Injector Actuating Pump (models 254-4357 and alternate part 10R-3144) is a critical hydraulic component
exclusively built for Cat C7 diesel engines. Designed to deliver precise high-pressure fuel supply to injectors, it features a robust gear-driven mechanism and pressure-regulating valves, ensuring stable fluid flow even under fluctuating engine loads. Constructed from heat-treated cast iron and hardened steel components, it resists wear, vibration, and corrosion in heavy-duty operating environments—extending service intervals and reducing maintenance downtime.This pump integrates with the C7’s fuel system to synchronize pressure delivery with injector timing, optimizing combustion efficiency for enhanced power output (up to 300 hp for the C7) and improved fuel economy. It complies with emissions standards by minimizing fuel leakage and ensuring consistent fuel metering. Ideal for on-highway trucks, construction equipment, and industrial generators, it comes with OEM-grade quality assurance and compatibility with Cat C7’s electronic control system, making it the reliable choice for engine performance restoration and long-term operation.
