Good vacuum gauge to help with FE
 

Autometer Gas Saving vacuum gauge
I like how it has the colored markings for a quick reference. Too bad it seems to be more expensive than a normal Z series autometer vac gauge :(
It would take a while to save enough gas to pay for that much of a price tag.

Maybe these are still for sale :

I used a cheap vacuum gauge from the auto parts store. It was around $15. It also does fuel pressure so you only get half the gauge face to be usable.

It is mounted on the top of the dash you can see it in this pic.

I almost got one off ebay. https://cgi.ebay.com/ebaymotors/ws/eB...2645&rd=1&rd=1 I need a better one for the Caprice. The parts store ones are ussaly ricer ones. This one is simple, and easy to read.

Wow! I was going to do a search, on "vacuum gauges" and I found this thread. I had one MANY years ago when gas went up in the 80's and if you watch it, it will help with your driving.

Egauges seems to have quite a selection

I bought a Summit brand one for $20. It has the 12V lighting and everything. I got one with white letters and a black face but they have them with white face and black lettering too. They show from 0-30 in Hg.
