9971792 12V Fuel Shut-Off Solenoid for Case IH New Holland Fiat Bosch VE Injection Pump

Product Overview

This aftermarket 9971792 fuel shut-off solenoid is a commonly replaced electrical component built for CNH agricultural and construction machinery. It mounts directly onto Bosch or VE-style diesel injection pumps, controlling fuel supply to the engine through electric on-off signals. When the ignition switches on, the solenoid energizes and opens the fuel path; once power cuts off, its internal spring resets to close the line for safe engine shutdown. Engineered to withstand dusty farm sites and heavy operating vibration, this shutoff valve delivers stable performance for long working hours. It supports a huge lineup of New Holland and Case IH equipment including tractors, skid steer loaders and backhoe loaders, and multiple cross-reference part numbers allow straightforward drop-in replacement during service and overhaul work.
