Fuel Shutoff Solenoid Valve 3018453 / 3035342 — Direct Fit for Cummins NTA855 & N14855 Diesel Engines

The Cummins NTA855 and N14855 are workhorses of the heavy trucking, marine, and industrial world — engines built to run hard and last. The fuel shutoff solenoid is the gatekeeper of the entire fuel system: when it fails, your engine won't start, won't shut down properly, or cuts out without warning. This direct-replacement solenoid restores precise electromagnetic fuel shutoff control, keeping your Cummins starting reliably, running safely, and shutting down cleanly every time.

✅ Compatible Cummins Engines

• Cummins NTA855 (all variants)
• Cummins N14855

🔧 Signs Your Fuel Shutoff Solenoid Is Failing

Engine cranks but won't start despite good fuel and battery, engine starts then immediately dies, engine won't shut off when the key is turned, or intermittent no-start conditions are all classic shutoff solenoid symptoms. On a big-block Cummins, these symptoms are often misdiagnosed as injection pump failure or fuel supply issues — costing time and money chasing the wrong problem. The solenoid is always worth checking first.
