FWIW as in misery loves company - My 98 Legacy 2.5GT has developed the same raw gas smell, I think it is at cold start-up. Going to check fuel lines, connecting hoses, evap can per all the other threads. I had a HUGE gas stink in the garage earlier in the year, that was successfully traced by my nose to the right rear, turned out to be a very rotted gas tank filler neck pipe
