Default Vacuum hose size
Does anyone know the vacuum hose sizes the blazer uses on the engine? I did my intake gaskets not long ago an noticed most of the vacuum hoses were old and starting to dry rot. I have a 99 blazer 4WD LT. Thanks for the help

Mainly, two sizes are used for HVAC & 4WD: 5/32" & 7/32".
