Length of boost gauge vacuum hose

Looking at the vacuum hose for my OEM sports meter boost gauge... it goes
from right in front of the firewall... out to the passenger head light... into the
front fender... then back into the center console to the boost gauge...

Would extra long vacuum hose make the boost gauge somewhat inaccurate??
I'm thinking if I should reroute the vacuum hose....

Thanks,

Nope, the length of the tube doesn't really matter. Mine is run the same way, and I have 19psi in max boost which is what it should be. As long as the hose isn't rediculously long, you will be just fine. Once the car starts and the hose is pressurized, pressure will fluctuate evenly throughout the entire tube.

So as long as you don't have any kinks or leaks, you will be fine.

Hmm... I did find another thread describing the Mitsubishi instruction on the
sports meter.... seems to be the same way like mine.
