Has anyone ever had to replace the high pressure fuel pump on a F-450? I was told you have to take the entire cab off to get to it?
2WD or 4WD? Engine size?
the fact that he mentioned a cab lift leads me to assume its a 6.4 liter PowerStroke. a depressing number of procedures on F-Series trucks equipped with that engine start with the words “Step 1: Lift cab off of frame.”
Are you talking about the high pressure oil pump used to actuate the injectors?
Have you positively verified the problem? Several causes can mimic a bad high pressure pump and can even throw codes for low injection pressure.
a 2008 with a 6.4 has a common-rail system instead of the HEUI setup on the 7.3 and 6.0.
