Lets start with this:

VACUUM DIAGRAM ACRONYMS

A/CL: Located in the air cleaner
A/CL DV: Air Cleaner Diverter Valve
A/CL BI MET: Air Cleaner Bi-Metallic Valve
A/CL CWM: Air Cleaner Cold Weather Modulator
ACV: Air Control Valve
AIR: Ford calls this the Thermactor, short for Thermal Reactor. CA vehicles are installed with it as standard. Air Injection Reaction is what it stands for.
AIR BPV: Air Bypass Valve (aka Thermactor Air Bypass TAB)
BV: Bowl Vent (on top of the float tanks)
CARB: Carburetor
CPRV: Canister Purge Valve
DIST:
EGR: Exhaust Gas Recirculator
EFCA:
FLTR: Filter
FPR: Fuel Pressure Regulator
IVV: Thermactor Idle Vacuum Valve
MAN VAC: Indicating Manifold vacuum-Vacuum source
MAP: Manifold Absolute Pressure
SOLV: Solenoid Valve
SV-CBV: Carburetor Fuel Bowl Solenoid Vent Valve
VAC:
VCKV: Vacuum Check Valve
VRESER: Vacuum Reservoir Solenoid Valve
VRV:
V CK V: Vacuum Check Valve
VRDV: Distributor Retard Delay Valve
TVS: Throttle Valve Solenoid (aka Solepot, Dashpot)
TVV: Thermostatic Vacuum Valve (aka Ported Vacuum Switches)
PURGE CV: Vapor Canister Purge Valve



Color Codes to do Vacuum Diagram
Red = Main vacuum
Green = EGR function
Orange = Heat control Valve (exhaust & intake) (AKA heat riser but more complex)
Yellow = Distributor advance
White = EGR vacuum (source)
Black = Mainly used for the Evaporative emissions control
Black = Thermactor ACV or Diverter valve
Blue = Throttle Kicker control
Pink = Thermactor Air Bypass Valve (BPV)
