Cummins Z14 engine parts fuel pump C5492102 in stocked

A core strength of the C5492102 fuel pump is its precise fuel delivery, tailored to the Cummins Z14’s high-performance demands. It maintains a consistent fuel pressure of 350-400 kPa (critical for the Z14’s direct-injection system) with a flow rate of 120 L/h, ensuring each injector receives the exact fuel volume needed for complete combustion. The pump’s internal pressure regulator adjusts dynamically to engine load—supplying more fuel during heavy acceleration and reducing flow during idle—maximizing power (up to 600 hp for the Z14) while minimizing fuel waste. This precision reduces exhaust emissions (meeting Euro VI and EPA Tier 4 standards) and prevents incomplete combustion that causes carbon buildup on injectors. For operators, this translates to smoother engine operation, faster throttle response, and up to 4% improved fuel economy

Built to withstand the Cummins Z14’s rigorous operating conditions, the C5492102 fuel pump uses industrial-grade materials. The pump housing is made of die-cast aluminum alloy (ADC12), offering high heat resistance (up to 150°C) and corrosion protection against diesel fuel contaminants. The internal rotor and gears are crafted from hardened steel (58-60 HRC), resisting wear even after 10,000+ hours of operation. The pump’s seals are made of FKM rubber, which maintains flexibility and fuel tightness in temperatures ranging from -40°C to 120°C—preventing fuel leaks in extreme weather. Rigorous durability tests (5,000-hour continuous operation, 1,000-hour vibration testing) confirm the pump performs reliably for 150,000+ km, reducing maintenance frequency and replacement costs for Z14-powered equipment

The C5492102 fuel pump integrates built-in protection against fuel contamination—a leading cause of Z14 engine damage. It includes a 10-micron inline filter that traps dirt, rust, and water particles before they reach the pump’s internal components, preventing rotor wear and valve blockages. The filter’s replaceable design allows easy maintenance without disassembling the entire pump, saving technician time. Additionally, the pump’s check valve prevents fuel backflow when the engine is off, maintaining system pressure and ensuring quick cold starts—critical for Z14 engines used in cold climates. For operators, this contamination protection extends the life of injectors and the fuel system by 30%, minimizing costly engine overhauls

The C5492102 fuel pump is designed for hassle-free installation and maintenance, optimizing uptime for Z14-powered equipment. It comes pre-assembled with the mounting flange, gaskets, and hardware (bolts, washers), eliminating the need for separate parts sourcing. The pump’s compact design (220mm×180mm×100mm) fits the Z14’s engine bay without interfering with adjacent components like the alternator or cooling system. Installation requires only basic tools (socket wrench, torque wrench) and follows Cummins’ standard procedures—taking 2 hours or less for a skilled technician. A detailed instruction manual (with torque specifications: 35-40 N·m for mounting bolts) is included, guiding proper fitment. This ease of use reduces equipment downtime, ensuring Z14-powered trucks or machinery return to service faster for time-sensitive tasks
