I lifted up the car, removed the underbody paneling covering the driver-side of the tank. It looks clean, but there is still a faint fuel-like smell coming from the fuel line area. Couldn't get a clear view of the top side of the tank from the endoscope. Smells a bit different than the diesel from the filler neck that's for sure.
Also while I had the car up on the air, I had a look at everything else and found out the panel covering the fuel filter is damaged. Last touched by an indy shop when the fuel filer was replaced.
