This gear-driven fuel pump, part number 3090942 (cross-referenced with ReCon part number 3090942RX and mechanical codes 3417674, 3417677, 3041800, 3075340), is a direct replacement for the high-pressure fuel delivery system on Cummins ISM11, QSM11, M11, and N14 diesel engines equipped with the CELECT and CELECT Plus electronic control systems. Note that this specific unit is the version without an integrated fuel filter housing base (often serviced as a bare pump with mounting gasket and drive coupler included).
Unlike standard low-pressure lift pumps, the 4010254 mechanical gear pump operates continuously during engine runtime to generate constant fuel system pressures ranging specifically from 250 to 300 PSI. This level of pressurization is required to supply the fuel galleries in the cylinder head, feeding the electronically controlled unit injectors (EUIs) at the precise flow rates mandated by the ECM. It mounts directly to the accessory drive gear housing of 10.8L (M11/ISM) and 14.0L (N14) inline-six blocks, drawing fuel from the primary filtration system to prevent cavitation at the injector nozzles.
Common failure symptoms of the stock transfer pump include internal gear wear, housing seal leakage, or pressure drops below 200 PSI, which trigger active Diagnostic Trouble Codes (such as low fuel pressure warnings), engine power sag under heavy load, and hard hot-starts. Replacing the worn assembly with this new 4010254 pump restores the factory fuel volume delivery curve. This guarantees proper fuel gallery charging, maintains standard horsepower output, and prevents injector starvation in demanding heavy-duty commercial truck and stationary generator applications.
