Product Overview

Part number 3054609, also widely referenced as 4024809, 3054610, 134074, 196066 or 3054607, is a 24 Vdc fuel shutoff solenoid valve assembly for Cummins PT fuel pumps. As the electronic engine shutdown device, it energizes to keep the fuel passage open and de-energizes to cut off fuel supply for safe engine shutdown once the ignition is turned off. Built for long-term reliable service in heavy-duty environments, this single-terminal solenoid features a rugged electromagnetic coil and mounting hardware; a rectangular sealing ring (121352 / 129888) is required at installation to prevent fuel leakage. It offers broad coverage across the Cummins diesel family, including NH855, NT855, NTA855, N14, K19, KTA19, M11 and QSM11 engines used in construction machinery, generator sets and off-highway haul trucks. It serves as a dependable replacement to restore normal engine shutdown and starting function where a faulty unit causes runaway, no-start or stalling issues.
