Gas Smell . .& not baked beans!

Hey Ya'll, How much of a gas smell is normal with my '37 Chevy 350 CID V-8 with 350 Turbo Trans? I've noticed even long after the engine has cooled down, I can still smell gas under the hood. Also, today after running it just a short time, I could smell a slight gas smell under the trunk area. Any dangers? Thanks, Donna

My 66 Chevy had a gas smell too. I noticed something dripping and staining the intake manifold and figured it was gas from the fuel inlet lines. Tightened these up and almost all of the smell left after I cleaned up the spots and it did not leak again. I would check for leaks anywhere the fuel can be like lines, fittings, the filter, around the tank etc. Here's another idea, maybe the fuel is leaking out of the fuel bowl into the manifold when the car is turned off? You know kinda like boiling out past some passage. If I spill a teaspoons worth of gas in my garage I smell it for 2 days so it don't take much to make a problem. Please keep all open flames away from the smell.

carb vent open ???

smog compliant carbs use a rubber hose to take the vapors back to the carbon canistor,,, engine heat can cause fuel in the carb to vaporize I think the new blend of gas has more stink juice in it
