I've been cruising your site here but couldn't find a vacuum schematic for an xj-12, inparticular the engine arena. I have a line off the right bank which comes from the manifold.
One manifold line goes to the valve in the air filter housing but the other is just floating in space but looks like it was heading towards the left bank of the engine.
Any help would be appreciated.

Thanks In Advance!!

A chap called Sean Straw provides some great info.

Great stuff, he just doesn't do the early carbureted versions and starts at about 1985.

I'll take photos of what I have on my 73 and forward them to him in case anybody needs what I have minus the one hose of course.

Still looking, anybody have or know where the vacuun tube goes??
