Purpose of the Part

The fuel metering actuator controls the amount of diesel fuel delivered to the engine's injectors. It responds to commands from the engine control module, helping maintain proper fuel delivery, smooth engine operation, and consistent power under different loads.

Issue Symptoms / When to Replace

Possible signs of fuel metering actuator problems may include:

  • Hard starting or extended cranking
  • Rough idle or inconsistent engine operation
  • Reduced engine power or poor acceleration
  • Intermittent engine stalling
  • Fuel delivery-related fault codes

These symptoms may also result from fuel pressure, wiring, injectors, or other fuel system issues. Proper diagnosis is recommended before replacing the actuator.

Brand Information

Cummins introduced its electronically controlled HPI fuel system with the ISX engine family in the late 1990s. Unlike conventional injection systems, HPI uses separate fuel metering and timing actuators to control injection quantity and timing. This technology allowed precise electronic fuel management while retaining mechanically actuated unit injectors.

Installation Notes
  • Fuel Contamination: Eliminate fuel contamination before installation to prevent damage or sticking of the replacement actuator.
  • Sealing: Use the correct actuator mounting gasket to prevent fuel leaks.

How to Identify an OEM Part

Look for the M-CUMMINS SCANIA HPL LLC casting on the metal housing and the manufacturer identification barcode label.
