Built for the CAT, the 3176389 fuel injection pump cat delivers steady, pressurised fluid to the engine's fuel or hydraulic system — a critical function for maintaining power output and operational efficiency. A failing pump results in loss of power, hard starting, rough running, and eventual engine shutdown — making prompt replacement essential to avoid extended downtime. Built to OEM reference 3176389 for accurate, no-modification installation on the CAT with full flow and pressure restored from day one.

Key Features:

  • Sustained Flow Rate: Provides steady, reliable fluid delivery to prevent power loss and maintain engine performance.
  • OEM Grade Build: Manufactured to reference 3176389 for direct, compatible fitment on the CAT.
  • Long Service Life: Designed for extended operational life under the continuous demands of heavy excavation and construction work.

The 3176389 fuel injection pump cat is a critical engine system component for restoring full fluid delivery performance on the CAT.

What Does This Injector / Fuel Pump Assembly Do?

Delivers a precisely metered, high-pressure fuel spray directly into the combustion chamber at the timing commanded by the ECU. Correct injector operation is critical for power output, fuel efficiency, and meeting emissions requirements.

  • Black or white smoke from the exhaust, especially under load
  • Rough or uneven idling with noticeable engine vibration
