anyone with VAC/BOOST gauge installed in car?

hey whats up. i have a 97 integra and im gonna hook up a vacuum gauge in my car. (Boost and vacuum gauges hook up the same way right?) well anyways im gonna mount it on my A-pillar using autometer dual gauge pod. my question is how do u run the vacuum line (the tube) from the gauge down to through the firewall? i was looking at the space where the A-pillar meets the dash and I dont think it's enough room for the tube to squeeze through there. how did u guys run this tube from the gauge itself to the engine bay? (Main problem im have n is figure n out how to run this tube from the A-pillar to the engine bay)

I have my boost guage in a cluster mounted pod, but I do have a shift light on my a pillar who's wires run through that crack, the nylon tube that comes with your guage is pretty strong, but it wont take too much pressure (coming in on it) before it kinks, I'd say take a small screwdriver and kind of use it like a drill, to make yourself a small hole in that little gap, it wont be visible because the tube will be there.

i used the thin plastic line that came with the guage, there was plenty of room for it to fit through.
