So im getting a maggie tvs1900 soon and have my gauges already installed and functioning. Well my vac hose from my gauge is wired through firewall but isnt long enough to run to my manifold. So i wont he able to use the port on the maggie itself. So then i looked at tapping into brake booster but the t fitting that came with the gauge is too small to fit the brake booster. I went to the auto parts store to look for a t fitting but no luck. What exact fittong goes in that hose? 1/2" or 3/4" ?

 

I would just extend my boost gauge line
to reach the new port

 

^^^^Same

 

I actually had plenty of line on mine, but still managed to kink it on a sharp bend. Cut the kink out and made a little elbow. No problems

 

where is a good place to get vacuum hose?
if I can find a t adapter at home depot ill just do that to the brake booster. closer to where I have it coming out of firewall and less points of failure.

 

You can just use a hose splice. Normal rubber hose will work fine since it will be such low pressure.

 

not a fan on putting it in the brake line.

 

I already did it in the brake booster line and it works. next up im putting in shift kit and servos.
