Hey so i picked up a boost gauge that i want to install after i did the super charger mod on my 3800n/a from zzp
It's a 2002 and I'm trying to figure out how or where to run that hose from, and where to plug it into, I'm assuming one end will plug into the t fitting leading out from under the snout into the boost gauge but most importantly how to get that dam hose thru the car lol

Thanks

 

I made a T off of the map sensor on the back of the motor so it was less line to run. I'll suggest going out and buying some black good quality vacuum line to do this with. I used the clear hose that came with my gauge and it got so hot and had so much vacuum that the hose actually melted itself shut.

As for running it inside, I think I popped a small hole in the firewall near that large bunch of wares that come through already, and then used a rubber grommet around it. Then just run it up through the drivers side fuse box and into the A pillar.

 

you should be able to T into any vacuum line and it will work (works like this on a turbo car anyway) as enzo said i also ran through the firewall where all the factory harness goes in. its at the bottom of the firewall pretty much straight down from the alternator.

 

A trick I use is to buy a piece of steel brake line and route it into the car. Bend as needed. That way you only need a couple short pieces of hose to make your connections.
