Strong fuel smell around vehicle jacked vehicle

The vehicle is a 2006 Chevy Cobalt, I have observed a strong fuel odor around the vehicle. After jacking up the vehicle I found some fuel seeping, apparently from the top of the fuel tank. Has anyone addressed this problem on this particular car? Also if I have to remove the fuel pump and lines do I need any special tools to remove the fuel lines?

I have the exact same problem with my 2006 chevy cobalt right now. That's why I am searching this. I had a mechanic friend look at it and it's the fuel pump and the lines are cracked to. Has anyone heard of a recall on this? It can't be a coincidence that we are having the same issue.

    Wife complained of fuel odor inside of car. Investigated and found fuel odor inside left rear fender well. Put the rear end of thecar up in the air on ramps and let the engine run. Saw fuel dripping along the fuel tank straps. Removed the tank and found the SUPPLY and RETURN lines connected to the fuel pump hose barbs loose and rotating. Fuel was seeping from the hose connections. Looks like the brillant minds at GM cut corners and "HEAT SHRINKED" the plastic fuel lines to the hose barbs. ended up replacing the pump and lines it came as an assebled unit. Took the leaking pump and removed the fuel lines with a utility lnife. Plastic hose barbs have an "O-ring" to assist in sealing. Conclusion: nothing wrong with the pump poor quality and design with the fuel lines and method of securing the lines to the fuel pump. Plastic gets old and brittle after time, GM cutting costs and corners. I'm in the aerospace industry, all fuel and hydraulic lines are SECURED / CLAMPED TO PREVENT LEAKAGE. There is a recall on 06-07 cobalt fuel pumps for cracked fuel lines and leakage. Get this, only certain VIN #'s and states. In the past 11 years I've purchased 2 silverados and 1 cobalt LTZ. Cobalt has been to the dealer for a recall on the elec. steering pump and failed wheel speed sensor affecting the ABS system. chevys are good for only 60,000 miles then, the trouble starts. I called chevy voiced my displeasure with there quality and said good-bye! Can no longer afford to drive a chevy. Have 2 Hondas in the driveway both have over 90,000 miles never seen the dealer or experienced a mechanical failure. Wonder what chevy did with the bailout money (our tax money)? Please pass this info. on I'd hate to see anyone else get stuck with high repair costs.

It could be hoses connected to the top of fuel tank from vent or fill since it only bothers when it is jacked up.. It is possible that rubber gasket on fuel tank pickup could be leaking, but if you have every driven in high water and splashed a lot it should have gotten water inside as well... So check fill and vent lines first. Have a good weekend!

2008 chevy cobalt has trouble starting and has a strong fuel smell

If the fuel system is dumping too much fuel into the cylinders, the check engine light should be on and you should be able to get trouble codes from the computer. The codes would point you in the direction of the problem.
Is the light on ?

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.

Strong gas odor but no leaks

I had an old chevy truck that was carbureted with a mechanical fuel pump. I drove for months with the same fuel smell. It ended up being a small hole in the pump itself, on the side of the engine. It evaporated too quickly from the hot engine temperature to catch. hope maybe that might help if you have a mechanical pump.
