Product Description
The Ford/Motorcraft 4C3Z-9B246-F STC HPOP Fitting Update Kit is the factory-approved solution to one of the most notorious reliability issues on the 6.0 Powerstroke. The original Snap-To-Connect fitting that links the high-pressure oil pump to the branch tube was prone to flexing, seal wear, and even total separation. These failures cause oil leaks that result in hard starting, no start conditions, or sudden stalling—sometimes without warning.
This updated kit eliminates the problem by adding a bracket that locks the branch tube and fitting in place, preventing movement and ensuring a reliable seal. It’s the best way to keep your 6.0 running strong and avoid dangerous on-road failures.
