6.0L Power Stroke STC Fitting Update Kit (high-pressure oil rail)

6.0L engines with the 2005-model-year HPOP redesign onward (2005-2007, plus late-build 2004 '2004.5'; also 4.5L Power Stroke and E-series through 2010). Structural fitment lists MY2005+ and E-Series 2005-2010; 2004 ('2004.5') builds have the STC fitting too, but no published build-date break exists - verify by looking at the fitting. 2003 / early-2004 engines used a one-piece threaded fitting and do not have this failure. The Motorcraft update kit 4C3Z-9B246-F reverts to a one-piece threaded design.
