I am going to see if "Prodemand" has a diagram.

Need to know if it is a 4.6 or a 5.4?

Any other designations of your rig might help me too!

They usually just go to the back of the intake manifold facing the intake manifold. Those hoses a trouble spot for those even the v10 the hoses have issues as well.

Yes, there is one that does, but there is also another one that goes to the very back of the engine block and the plug looks like a spark plug boot but hours onto a nipple some were l have a 2002 F150 5.4 I followed that one, but it ties into a hose on a tee but the 1998 is not the same fitting. I not know. I see the one that goes to the top upper intake but there is another one heading to the back?
