This is a follow-up to my post of 3/8/2012.

I got the 2.5" flex hose and reworked how my snorkel is
connected to my dust trap (cyclone) and how the dust
trap is connected to the air box (Kennedy Subie conversion
airbox) and how the airbox bracket is mounted.

In short--the 2.5" heater/airconditioning hose is different
from the original VW hose, but should work fine.  I'll see.
