So my car shut off on me after the tank was marking at half a tank but I had no gas so I scheduled it for service and they replaced both sending units, everything works fine but service advisor tells me upon arrival to leave the windows down due to gas smell so I left them down overnight and also cleaned behind the passenger seat and the carpet area, I left for vacation a day later for 8 days and I left it in the garage with the windows half way down and I return but it still smells like gas especially when I leave the car and get back In it later. The gas smell definitely went away a little compared to when I picked it up but it's still there, could this be that a seal was messed up while the sending units were being replaced or just some gas was spilled somewhere??? Kinda frustrated
