Could not figure out why I was using/losing gas. Then recently I could smell gas but never could see anything, and when the car was not running there was no smell or visible leak. Today I let it run in the driveway and saw gas leaking from the rear/tank area. I guess it only leaks while under pressure. Any thoughts? Looks like it's off to the shop Monday, this may be above my pay grade to fix! Maybe a seal or the line?? Thanks Tom.
