Product Description

The Exergy E05 10305 inlet metering valve is a direct replacement for the factory MPROP on 2006-2010 LBZ and LMM Duramax trucks, addressing common symptoms like idle lope, surging, and inconsistent rail pressure caused by a worn or contaminated spool valve. As the component that regulates fuel flow into the CP3 pump, a failing MPROP can cause serious drivability issues if left unaddressed.

Because MPROP-related symptoms can overlap with other fuel system issues, a professional diagnosis is recommended before replacement - this part isn't returnable once installed if it turns out not to be the cause. For confirmed MPROP failures, though, it's a straightforward, OE-style fix that restores proper fuel control on these LBZ/LMM Duramax trucks.
