Original PT Diesel Fuel Injection Pump 4951495 — Precision High‑Pressure Fuel Delivery

If your diesel engine is showing low power, hard starting, unstable RPM, or excessive smoke, the issue is often traced back to a failing fuel injection pump.

The 4951495 PT Fuel Injection Pump is engineered to restore precise fuel delivery, ensuring your engine operates with the reliability and efficiency demanded in heavy-duty environments.

 

🔧 Designed for Real-World Diesel Challenges

Unlike generic aftermarket pumps, this unit is built specifically for Cummins PT (Pressure-Time) systems, where fuel delivery must match engine load mechanically and instantly.

✔ No ECU dependency
✔ Immediate throttle response
✔ Stable fuel pressure under load
✔ Reliable operation in extreme environments

If you're experiencing any of the following, this pump is likely the solution:

❌ Engine lacks power under heavy load

❌ Difficult cold starts or long cranking

❌ Excessive black smoke or incomplete combustion

❌ Fluctuating RPM or unstable idle

❌ Increased fuel consumption

👉 Fix the root cause - not just the symptoms
