Other Fuel System Hoses Lines/piping, And Fittings problems of the 2009 Chevrolet Cobalt

Keep smelling fuel vapors on the rear left side of the vehicle. Checked the fuel filter and it seems to be working despite my gas mileage getting worse and worse. I've been burning a full tank of gas going less than 250 miles when I should get near 400 miles a tank.

In my 2009 chevy Cobalt, I recently noticed a very strong gas smell when getting out of my car after a short trip. Yesterday, after I backed the car out of the garage to install a new car seat for my one year old son, I noticed the smell again and noticed a large puddle of gas dripping at a pretty fast pace. After investigating, I noticed it coming from a section of rusted fuel line near rear driver side tire. After looking for recalls and service bulletins, I called a local chevy dealer and they said the leak was not covered by any recall or service bulletin and it would cost about $850 to $950 to replace the entire fuel lines from engine to gas tank. I noticed hundreds and hundreds of similar issues documented on various automotive web chat sites describing the exact same issue in the exact same place for Cobalt's from 2006 to 2010. There is what appears to be an insulator around the lines to protect them from the exhaust pipe heat that accumulates road salt and moisture over time and corrodes the fuel line at that specific location. Needless to say this issue presented a very serious condition that could have jeopardized the lives and safety of my children as well as my wife's and my lives. My car is now useless until I can save enough money to pay for the repair.

I began to smell gas after exiting the vehicle. I traced the smell to an apparent leak coming from the top of the tank where the lines from the fuel filter are routed over the top of the tank. I discovered the recall for fuel pump plastic part failures in warm weather states, also 2009 Cobalt, but, georgia is not listed (I'll tell you it is a warm weather state). Also, in regards to another individual's complaint NHTSA id number: 10668977, I discovered my tpms were backwards about three years ago when I had an unexpected flat. The low pressure indicated by the tpms directed me to the wrong tire. One of the tpms stopped working within days of driving the car off the lot. Other issues: 1) multiple times I have placed a small item like a phone in the passenger seat and the passenger air bag turns off - seems hyper sensitive, not nearly the weight of an infant 2) my front speakers don't play unless the weather is warm (wiring harness/connectors?).
