I looked in my parts and illustration guide for my 56 fairlane but the part numbers cover 4 different sizes of 100ft spools but doesnt state what size for what area.

Does anyone know what size the vacuum hose is from the temperature control valve in the heater plenum to the heater valve on the intake?

What about the vacuum hose size from the wiper motor tee to the temperature control valve?

Mine is brittle and falling apart but its so old it predates the marked hoses so i dont know. Cant buy locally here true vacuum line so want to order it when i order the 5/8 white stripped heater hose.

So if anyone could help with what sizes vacuum hose was used where i would greatly appreciate it.
