Yea, that's a manifold vacuum guage, useful for tuning carburetors and monitoring economy.If you rip it out make sure the manifold is plugged where it is tapped or you will encounter a serious vacuum leak.

It looks like it's an aftermarket vacuume pressure sensor. by the looks of it, it hasn't worked in some time.
They don't come stock, so you could get rid of it.
If you wanted to, you can always get a new one later on.

I didn't bother even checking to see if it did anything when the car was on, but would it work just like that? Does it not require any other kind of power or anything? Does anyone have a link where I can maybe learn about what this does so I can decide whether it's worth keeping or not?

Joel, the only power required is for the light inside the guage (12 VDC). The guage indicates the vacuum in your intake manifold, which changes constantly due to rpms, throttle opening, whether you are cruising , accelerating or decelerating. All these dynamics influence manifold vacuum, which is very improtant to meter the correct air/fuel ratios and also controls vacuum advance system in your distributor. If that hose connects to your motor near the carburetor you need to make sure hole is plugged or leave it connected.

tear it out, and put a plug on the engine where it hooks up. If it is still hooked to the engine of course.

I actually checked it out, did a little research, and started her up and she sat at a steady 18, and I read that that is ideal.... sooooooooo I threw a ring on er' (screwed her into the bottom of the dash lol)

Matty, have you converted to the new dot 7 headlight fluid yet? Tests showed that the dot 6 held too much moisture & caused premature muffler bearing failure. Thought you might need to know that.
As far as dash mounted vacuum gauges go, the idea is to drive as light footed as you can to keep the reading high for better fuel economy.

jlcustomz,, Thanks for the info!!!!!! I will go to dot 7 this weekend!!!!
Gary,, the vaccum gauge needs to be hooked up to the manifold vacuum, not to the carb,, behind the carb where the tranny or p/b booster hooks up to. Matty man
