2006 Ford F250 Super Duty 6.0 turbodiesel.
Where is the HPOP located on the engine, so I can see if it has been updated? on 2005 Ford F-250 Super Duty
hpop is located under turbo. turbo has to come off, then there is a cover for the hpop. if vehicle is high miles, chances are it has been updated, as the snap to connect fitting originally used lasted about 100k miles.
