I second the roll of vacuum line, and fuel injection line.
There's also a hose that goes from the bottom of the intake manifold to the crankcase breather vent - I've yet to own a Z that didn't have problems with that hose. In a pinch, it can be replaced with a cut-to-length rad hose out of a Honda - if you talk the auto parts store guys into letting you look in the back, it's the big long one that goes from about an inch diameter to 3/4 (if memory serves).
