This is a replacement 12-volt fuel shutoff solenoid commonly used on Cummins diesel engines. It's a direct replacement for part numbers 4024808, 3054611, 3054608, and 3408421 (always double-check your specific engine's part number to ensure compatibility!). This solenoid is a critical component that controls the flow of fuel to the engine; when energized, it allows fuel to pass, and when de-energized, it shuts the fuel off. A faulty one can cause starting problems or engine shutdown. This listing includes just the solenoid itself (1 piece). Please note: No installation manual is included. Working on fuel systems can be complex and potentially dangerous, so professional installation by a qualified mechanic is highly recommended unless you are very experienced. A crucial part for getting your Cummins-powered truck or equipment running smoothly again.
