As I said, I am currently searching for the locations that these lines belong in. I tore this engine down over 3 years ago due to headgaskets as well as a cracked piston and just left it to sit. Ended up finding a long block for sale for $3,000 and jumped on it. I cannot for the life of me recall how these vacuum lines go or where this coolant line off of the throttle body goes to... I know that the vacuum lines run from the booster and to the pump but unsure how they sit in the bay or where the third line goes to. any help would be greatly appreciated! It's a 2013 awd xf 3.0.

 

i believe the coolant hose goes under the supercharger to the back of the block, would this be correct?

 

In your top picture the tube clips into the rubber cam cover on the passenger side of the engine.





Here is the drivers side with the rubber pad on. Do note the labels!
I saved this picture because one guy got those two lines crossed and he pumped gas into the vacuum port. Surprisingly the engine still ran but was being drowned in gas!




This is on my 2014 XJR but what your working on would be the same or very close.

I think your right about the coolant hose but have no pictures to help.
