I need to add a vacuum for my brake servo and wondered where the best place is to add it and what is the best way of going about it?

I have found a one way valve to stop any positive boost going in to the servo.

The servo is off a 205 gti (my car is a cossie engined pug) and I have added a 405 master cylinder as they are bigger. https://passionford.com/forum/restor...ng-gear-9.html

 

best place is plenum cover ,but better still fit the cossy pedal box pump assembley

 

I actually have a cossie master cylinder mated to a pug pedal box from the original conversion but I have binned the abs although I believe you can still fire up the pressure accumulator so I could have a go at wiring that in to come on with the ignition although never liked the noise they make at start up and seemed to put a big battery drain in.

Thanks for the advice re the plenum, I wondered if there were better or worse areas in the plenum but I guess adding it where the other sensor holes are should be fine?
