Vettestr - thanks for the tips. I plan to pull it apart this winter and at least add a gasket.

Rick - I will add the hose clamps on the vent lines and I will look into the large fill hose, when I take it apart. The stripe you mention may be turned to the back. I'll see what a mirror and flashlight shows. Thanks for the input.

I'm not 100% sure I have found all the sources of the fumes. When the trunk lid is closed for a day the fumes are stronger than when it is open, but that may be coming from the carpet and padding.
