Fuel pump failed
While fueling there seems to be a backlash air bubble that occurs and it takes approximately 10 minutes to put $30 worth of fuel. while pumping the gas no matter how slow or fast as the safety is in place to stop the fuel from coming out of the fuel neck where it meets the fuel going in this is normal to kick off the fuel so spillage does not become a problem however when you stop fueling there is a burp back as in a air bubble that splashes outside the vehicle which could potentially splash in a face or on your skin and it also runs down the side of the body of the vehicle again that is when fueling has stopped it burps the fuel out of the vehicle. obviously the vehicle is stationary while fueling. this occurs no matter what gas station is used old new it doesn't matter.
There is a fuel smell that occurs when vehicle is running and immediately when ignition is turn to on position especially on the driver side of the vehicle.
The defective fuel lines rubbed together and caused a leak. i paid a local dealership about $1100 dollars to replace the fuel lines as it was unsafe. my vehicle is not under a recall but in researching, it was discovered that others have a recall. i opened an incident with chevrolet as a defect but they were not able to assist as my truck is over 70k miles and pasted the warranty, the fuel lines are next to the catalytic converter and would have caused a fire.
Vehicle running fine and no warning lights - noticed fuel smell in garage and took in for oil change and see what's up - found the entire top of the fuel tank was a puddle of fuel and was running down sides. had the tank dropped and found the top of the fuel pump was rotted away where the pressure and return lines exit pump and before they attach to the plastic fuel lines. only leaks when vehicle running so had no spots in garage but was leaking alot while driving - 25 mile drive to shop used 7 gallons of fuel. *tr
Driving home from work, i notice a raw gas smell. pulled into my driveway, left the truck running and got out to see what was going on. looked under the vehicle and saw gas pouring out. stopped the engine and got under the truck for a closer look. upon inspection, i noticed that the two plastic braid over rubber fuel lines were coiled over each other causing them to rub, wear away the plastic braid and rub the rubber hose to the point of creating a hole. this is where the gas was spraying out from, right neat to the exhaust pipe! i immediately got out from under the truck for fear that it might ignite. looked on-line and saw multiple complaints exactly what i found on my inspection! *tr
