I have checked fuel pump and filter behind rear wheel, no leaks. I don't see any fuel dripping or puddled under car after sitting overnight. Where is the EHA located, no detectable gas smell under hood but worth a check even though car runs great w/no driveability problems other than odor when sunroof is opened.
