Vacuum gauge Mitsubishi Lancer

I bought a mechanical vacuum gauge with a T connector. I searched on alot of places but I really cant decide which hose to connect the T in?

I found a shabby picture of the exact car that I have.

I think that I should plug it in somewhere around the ECI MULTI but is there anyone who can say which line is correct? I dont want to break a fuel line or something!

Green arrows show the way
The most reliable source of manifold vacuum is the brake booster hose. You will probably need to buy a tee that will adapt between sizes. Be sure to use clamps so you don't lose brake vacuum when you need it the most :eek: .

Usually any line that has a high vacuum at idle is good. As long as your show a vacuum at cruise that goes to zero at full throttle you probably can use the gauge as it is just a relative indicator of engine load.

The power brake line is a good source but I usually refrain from cutting into that line in the interest of brake reliability.

Look for a line that goes into the intake manifold some place rather than into the air body.

This looks like a good place to Tee into.
