anybody now where i can find a vacuum tubing diagram

Hey there,

you'll have to state what model your Z is, but here is one for a 280z if that so happens to be what yours is.

However, that's an HVAC vacuum diagram and his car probably doesn't even have AC. We seem to get that (or something like it) whenever someone just wants an underhood simple vacuum diagram. That said, we'd still need to know what year.

You know, this comes up often enough that we need to deal with it properly. The lack of diagrams in even the factory service manuals is a problem.

Perhaps those of us who own stock, unmodified cars could draw up a diagram, one for each model year. I can do this for a US market '71 240Z, who else wants to take a stab at this?

Wow! I been askin for that for months! I'd do a 76 but mine is all messed up.

75-78 I can do. I've posted them a couple of times over the years on this site. It's the earlier ones that are hard to find.

Do you mean tube or hose ? Sorry, couldn't resist. Had an college roommate once with a '48 Pontiac Businessman's Coupe, it had vacuum tubes, but they were in the factory radio.

Sorry about posting that diagram, I was using that one for my car and just automatically posted it. I should have asked first what model car you have.

I am replacing my tubing soon, so I will be doing this anyway, and I guess I can just post it here. I have a 1983 280zx

its a 71' 240 z

280ZX vacuum diagrams aren't that difficult to find. They're in the FSM Basically, anything 1974 and down is where it gets kind of sketchy.

That's funny!

BTW, could someone post the cavuum diagram fior the engine on a 78? If there's onw on the underside of my hood, then the PO covered it with undercoating. :hurt:
