vacuum Guage

[ukm5]

how would i connect a manual vacuum performance guage to an M20 engine?

yes i know i have one on the standard cluster but i have a hole to fill on my new Guage panel and this looks cool!

You mean that MPG thing in the middle for the tach?

Hell, I'd trade that useless thing for something that provides valuable information. Like Oil pressure, or even barometric pressure,

Try hooking it up off of the brake booster manifold nipple.

T into the fuel pressure regulator line, the mpg gauge in the bottom of the tach is not vacuum related it's actual mpg computed by the fuel injection system
