Dash / chassis air conditioner on FC

[fwernlein]

Alan, I had the same concerns when I did my dash AC. I decided to go
ahead and rely on the existing hoses as they were well protected
from exposure to UV/Ozone being run interior to the bus; that they
held a vacume; and that I saw no way to get them replaced easily, my
best thought was if needed run new lines up the windshield center
seam or along a side pillar and cover up with some trim material.
My AC hose guy pointed out that the possibility was that although
the hoses were 20 years old, they likely had not been in
actual "service and pressure load" for a big part of those 20
years....and had a even chance of working out OK.

I have enjoyed dash ac for two summers and love it. I just have to
live with the possibility of hose failure...all in all...i would
recommend not bending/flexing them, do a good flush, pressure test,
and if it the hoses hold...go with it. Someday I'll be doing phase
II (hose replacement), but I'll wait for it.
