Blew while running. The heater was on and producing heat during the winter.
spewed again while running this morning, but was not running heat.
'73 V8 302 Has A/C but belt is off and hasn't been run in years(I assume)
After looking more closely, It may be the vaccum activated heater switch on the firewall.
The hose that blew before was between the switch and the engine.
