I constantly smell gas while driving, idling, or sitting parked.
Any ideas?

Mostly from under the hood

 

A gas leak.

Typical culprits include the weld where the filler neck connects to the tank cracked; the rubber lines that go from the tank to the steel lines that run along the body; bad fuel pump; improperly operating charcoal canister.

 

I just edited my first post, i smell it from under the hood. Think somethings up with the carb?

It's a 4 barrel 305 on 86 TA

 

From my experiance with my gremlin, go out and replace every single rubber connection going to that carb (fuel line that is) and just save yourself some trouble either now or later on. I kept trying to just fix one line at a time and ended up spending alot of lunch's at school fixing fuel leaks and smelling of gasoline for the rest of the day. So yes, its probably from the carb fuel lines. A few bucks in hose and make sure you have some good clamps and you should be in buisness.
