Vac Hose size #'s in FA???

[SJ]

I think the first dimension is the ID. Thats the critical dimension for
proper fit.

> Anyone know what those numbers for vac hose size in the FA mean? I usually
see something like 3.5x3 or 4x3, but I'm not sure if the first would be ID
or OD... I'm guessing the second number is wall thickness??? Anyone know
what it's s'posed to be?

cars. I'm going to try the dealer, but I have  bad feeling about it...I'm
hoping to find some other place for that. I've tried standard US hoses, but
they seem to work better on the larger hoses, the vac hoses are harder to
get a good fit. TIA.
