2007.5-2012 Cummins 6.7 Inlet Metering Valve (FCA/MPROP)

Do you have an engine lope at idle or surging while driving? Are you seeing unusual rail pressure fluctuations? Your 6.7 Inlet Metering Valve may be the root cause.

Also known as the FCA (fuel control actuator) or the MPROP, this component can wear from age or poor fuel quality causing inconsistent travel in the spool valve. The MPROP controls the flow of fuel to the CP3 pump. A crucial part of the high pressure fuel system and if not functioning properly can cause severe running issues.

Note: A professional diagnosis is recommended to ensure the MPROP is the cause of your issues. If mis-diagnosed and the MPROP does not fix your issue it cannot be returned once it has been installed.
