1998 C70 coupe. Which line do I tap into to install a boost guage. MY gauge has the lower part as a vacumn and the upper as boost. I am assuming that most lines have negative pressure, so which would produce boost pressure??
Thanks
Dwight

Dwight,
I just tapped directly into one of the spare ports on the vacuum tree. Uncap one of them and hook up directly to it. It works well, then you don't have to use a T-tap.
