PCV Hose on Classic

[Slamtry]

Doing a little maintenance, I just replaced the hose leading to my PCV
valve. I just used a length of fuel hose of the appropriate inner and
outer diameter, but I did wonder if it was meant to be a shaped(pre-bent?
I don't know the right term) hose from the dealer. Can anyone tell me?
Also, with the hose off, I get vacuum at the hose, NOT at the valve. This
is the opposite of what the FSM says. Can anyone confirm/explain?
TIA
