I've not seen vac layout diagrams. Couldn't you replace them one at a time as you take them off and then you wouldn't need a layout? I'd say the only place it may be is in the factory service manuals.

I know I posted this list a while ago. Here's what's on my '92, and your '91 should be similar. You should have vacuum lines going to:
1) Automatic transmission (if equipped).
2) Cruise control (if equipped)
3) brake booster
4) fuel pressure regulator
5) air filter housing
6) vacuum reservoir and HVAC system (1-6 coming off of vacuum tree at rear of intake)
7) PCV valve (separate nipple)
8) EVAP system (likely off of throttle body)
