    Probably on the frame rail under the driver's side rear door. Depending on model and year, either one quick-connect and a flare fitting or 2 flares. maybe a retainer strap.

    Car up on a lift and 3 oz. of gas in your face.

    Pray that it isn't rusted to the lines. Use plenty of PB Blaster for a few hours before trying to disconnect it.
