Boost Gauge Hose Routing in the TT

This is a brass "T", used on the primary vacuum line

This is the primary vac. hose.

The main line coming from the manifold, is at the bottom here. It has the enlarged curve at the back end, because I did not trim the hose, when I added in the "T" connector. I may trim this later.

It comes out through the firewall in the car here.

As far as the electrical goes, it's simply connected to the dash lights.

There are no electrical connections to the actual boost gauge itself.
