vacuum gauge 'cool factor'
Posted 25 October 2005 - 06:10 PM
These 'fuel economy' gauges operated on the principle that intake manifold pressure is directly propotionate to fuel consumption.
I've read that aside from the novelty value, a vacuum gauge can be useful in diagnosing all sorts of general engine health things from worn rings, to blown headgaskets to sticky lifters.
All of the gauges in my '87 GL wagon work It is nice having real gauges (versus warning lights) for temp, oil pressure, voltage and of course fuel.
I've been wondering about adding a vacuum gauge somewhere in my dash or under the stereo just for kicks.
Has anyone else added a vacuum gauge and if so, where did you install it and what brand did you purchase. Did you install a "T" fitting where the PCV valve is so it monitors pressure at the intake manifold at the base of the carb?
Thanks in advance.

I pulled a cat out of my bung-hole. No really, I'm serious.

Here is where my gauges are mounted. If you would like I can dig up some more detailed shots. The tap for the vaccum signal is located on the Automatic tranny vaccum feed (rear center of intack manifold)
Thanks... that's helpful.
