Boost Guage

[Renault 5 GT Turbo]

I want to replace the boost hose that goes into the back of the standard boost guage. Where does this connect to in the engine bay?

O.e boost gauge connects to a t-piece that goes to the drivers sideport of the carb top.

It passes through a grommet seal just to the inside of the brake servo, along with the shielded cable going to the speed sensor.
