Dealing with a Perkins or Woodward engine that won't shut down properly? This fuel shut-off solenoid might be your fix. It's a direct replacement for a bunch of part numbers, including 1502-12C6U1B2S1A, 1502-12C6U1B1S1, SA-2944-T, and others (check the full list to match yours). It's designed for 12V systems and fits specific Perkins engine series like the 4.165 and T6.3544, as well as some Woodward engines. This solenoid is what controls the fuel flow—when it gets the signal, it shuts the fuel off to stop the engine. It's built to be reliable and durable, even in tough conditions. Installation is pretty standard if you're familiar with engine components; just make sure to disconnect the battery first. Always double-check your old part number or take a picture to confirm this is the exact match before you buy. Having a functioning shut-off solenoid is crucial for safety and proper operation, especially in industrial or generator applications. Don't let a faulty solenoid leave you stranded or cause bigger issues. Keep your engine running smoothly and shutting down when it should. A solid, aftermarket replacement that gets the job done without the OEM price tag.
