Strong fuel smell from right side of car after driving and being parked. felt over top of tank and felt some fresh damp gas residue, not wet, just a little oily and damp. this could be from a liquid or a vapor line.what is the most common component failure that causes this and what are the other possibilities as well. thanks for your time.

SOURCE: Gas smell from car after driving

busted fill spout as if gets hot pressure builds in tank causing the smell

SOURCE: is it safe to drive car if brakes caught fire - still has lining!

I would suggest that you adjust your rear brakes. Most likely you have drum brakes in the rear. When the rear brakes are out of adjustment (caused by not using "e-brake" when you park the car. The "e-brake" when applied keeps the rear brakes adjusted with a self adjusting mechanism.) the front brakes have to do ALL of the work to stop the car. In this case going down a steep grade for a long time simply overheated the front brakes. When the front brake pads overheat they get "glazed" and don't want to work anymore. Most likely reason for brake pedal going to the floor is the brake fluid was boiling. Hope this helps. Good luck.

you have a leaking fuel pump, get to a dealer right away it will get worse!

SOURCE: strong gas smell coming from my cobalt at all times

Look in the back of the car. The fuel pump lines like to break. You will not be able to see them, but you will smell and see that the fuel tank is wet. Call your local dealership, have you vin # and milage, ask them if it's covered by warrenty.
