The Ford 6.0 STC HPOP Fitting Update Kit 4C3Z-9B246-F is the redesign of the high pressure oil pump for 2005 and newer Power Stroke diesel engines. The "snap-to-connect" or STC fitting used to connect the high pressure oil pump to the oil supply branch tube has been problematic. The two piece fittings have a tendency to flex causing wear on the seal and the locking ring resulting in leaks and occasionally the complete separation of the fitting. When a leak occurs at this fitting, the engine may be difficult to start or may not start at all. Depending on the severity of the leak the engine may stall, sometimes abruptly and without warning.


The Ford 6.0 STC HPOP Fitting Update Kit 4C3Z-9B246-F is the most current version available to service failed Snap To Connect or Quick Connect fittings on 2005 through 2007 Ford and International trucks.

The included bracket is designed to support the fitting and branch tube and eliminate the possibility of the fitting to become separated.

The Ford 6.0 STC HPOP Fitting Update Kit 4C3Z-9B246-F contains:
1 Support Bracket
