hey guys does anyone know what size the vac hose to the brake booster on top of the supercharger what size that would be? And if 1/4" woukd take care of the rest of line going atounf and under the supercharger to that tee? Im trying to replace all vac lines and tees and possibly looking where to tee in a boost gauge in the process. Thanks!
 


pull a line off and take it inside to a parts store match it up, or they will give you little test pieces you can take out and test fit. advance auto sells the best T's, they have a wall of vac t's y's and so on, small white t's two in a pack, for 2 bucks.

you can add the boost line t in the vac line under the snout to the map sensor.
