119-8770 Metering Pump — Cat 3306

This metering pump is an essential part of the engine's fuel system, precisely controlling the amount of fuel injected into the cylinders. Manufactured to meet OEM specifications, it ensures accurate fuel delivery for optimal combustion, unlike a worn pump that can cause inconsistent fuel flow. Operators may notice poor engine performance, increased fuel consumption, or difficulty starting if the metering pump fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a failing metering pump is often a noticeable drop in engine power or erratic idling. If left unaddressed, this can lead to increased fuel consumption and potential stalling. The worst consequence of a failed metering pump is the inability to start the engine or severe engine damage due to incorrect fuel delivery.

Installation Tip

Ensure the fuel system is properly bled of air after installation to prevent cavitation and ensure smooth operation. Do not reuse old fuel filters, as they can introduce contaminants.

Service Note

Replace the fuel filters and inspect the fuel lines for any signs of damage or blockage when servicing the metering pump.
