Thanks guys! Let me know if you think I'm missing any parameters that should be taken into consideration when trying to make this measurement.

Probably the most important property for the pressure sensor you select for your application is it's compatibility with the media it's measuring, gasoline in your case. Make no mistake that the required diaphragm isolated barrier is what makes such sensors cost significantly more then the sensors with no such barrier protection for the sensing element. You tend to get what you pay for in this line of sensors. Lefty
Well when I think of "old cars", it is not fuel injection that I have in mind.I guess 3 bars sounds high , if you don't have fuel injection, and it sounds low, if you do have fuel injection.For antique 1969 fuel injection, it probably sounds about right.
the simplest solution (I think) would be to use an analog oil pressure sensor

So something like this perhaps?http://amzn.com/B00029JXMA It certainly borders on cheap enough to play around with, but I don't like burning $20s either if someone can tell me that's all I'd be doing
However I doubt they are fuel proof, but if you isolate the fuel so only vapor makes it to the sensor, you might make it work. a length of hose, and vertical placement could let you get by for a while.
