Restore proper turbocharger boost control on your 1999.5-2003 Ford 7.3L Powerstroke with this Genuine Ford OEM MC3Z-9E498-A Vacuum Harness (Connector). This updated OEM replacement supersedes the original F81Z-9E498-DA and is engineered to meet Ford's original specifications for fit, durability, and performance.
This molded vacuum harness connects the engine's vacuum system to the boost control wastegate solenoid and related components. Over time, the factory plastic vacuum lines become brittle from years of heat cycling, often cracking or breaking during routine maintenance. A damaged vacuum harness can lead to improper wastegate operation, low boost, reduced engine performance, diagnostic trouble codes, and poor drivability.
Unlike universal vacuum hose repairs, the Genuine Ford assembly features the correct molded routing, factory-style connectors, and OE-quality materials for a direct plug-and-play installation.
Whether you're restoring your 7.3L Powerstroke to factory condition or replacing a broken vacuum line during turbo or engine service, the MC3Z-9E498-A is the correct OEM solution.
