vacuum line markings

does anyone know what the designations mean on the small (~4mm inside diameter) rubber vacuum lines under the hood?

they're labeled as:
#*
#1
#2
#3
#4
#5
all the same size.
do they refer to or support different systems? e.g. egr, efi, etc.

thanx in advance for looking!

also looking for a good replacement source for all the vacuum lines. i'm finishing up a reman engine job and am close to the finish line. these vacuum lines look to be in pretty good shape when you consider they're 16 yrs old.

thanx for looking

I don't know what they are for, but I made sure to take pictures of where they hooked up when I disconnected them.
