Fuel Pressure Relief Valve Question


New member
Hey there! New to the forum... have been reading about the Fuel Pressure Valve replacement on my recently purchased 04 158 hight top. Purchased part and now ready to install. Do I need to remove anything to install? I felt along bottom of high injector pump and could not locate a bolt sticking out. Have looked at diagrams and am thinking mine does not have the valve installed. Is that possible? Thanks in advance for any help or suggestions.

Give us a chance, which motor? Are you talking about a relief valve or the pressure regulating valve? What is the reason you want to change this valve? Eric

My 04 had this done by a dealer under a factory recall program. No charge. I bought the vehicle used.
