Hi everyone,

I'm looking to fit a turbo boost/vacuum gauge to my 147 JTD but am confused as to where to connect the vacuum pipe bearing in mind that it has to pick up the inlet vacuum as well as pressure.

There are 3 small pipes coming from the vacuum reservoir,
1 goes to the throttle body,
1 goes to a T-piece of which one end goes to the vacuum pump on the end of the camshaft,
1 goes down to the air box.

Does anyone know which of these the gauge pipe should be connected too or doesn't it matter?

Cheers!
