Does anyone know where to get these two "L" fittings?
They are on the drivers side of the intake manifold, pushed onto the nipples that point to the drivers fender.
On my 2000 4.0.

 

I can only help with the one in the center. Dorman 46022 or at Napa NOE 6301670. It is supposedly for a Ford but it works. Used it on my '00. The line in front can just be replaced with a piece of vacuum hose. That is because the nipple on the manifold and the hard plastic line are the same size. Not the case with the middle one which is why you need the Dorman elbow. Never messed with the elbow that has the white and black check valve in it but willing to bet there is a Dorman part on the help wall that most auto part stores have that will work with that one too.

 

I've got them from the dealer before as well as the junk yard

 

I have also grabbed them from a junk yard.

 

yah.. it's just one of those things you grab by the handful every time you find an xj in a junk yard. That and fuses, hose clips, light bulbs, lengths of wire, bolts.. you know.. stuff.
