Diagnosing a slow fuel leak

Have you checked the fuel line where it connects to the carb? Also, if you have the plastic clear fuel filter (replace it with a metal one) but check if it holds fuel after the car has been sitting.

First off, thanks guys for the responses. If you haven't my posts on my car before, she gets really bad gas mileage (avg ~8 mpg using premium fuel), and I've slowly been trying to address everything that could cause this, especially since gas is about to hit $4/gal in PHX.

The carburetor is a new Edelbrock. I replaced the fuel filter a few weeks ago to one of the plastic ones, and I want to put a metal one back on (hooray for getting a paycheck again). I just replaced the distributor and did the timing last night (currently at 10* btdc).

My next step will be doing the fuel line, as my housemate will be redoing his 76 F150 in the near future as well. Time just isn't conducive for that with work right now. I'll check out some of the things you have brought up and post pictures, maybe you'll be able to give me some more pointers then.

Thank you for the help, I'm definitely not the most mechanically inclined guy around.
