This may be one of these "known issues" = that I was=20 just clueless about, but a couple of weeks ago I arrived at the hangar = to the=20 strong smell of fuel in the air. Uh oh.

I thought that perhaps moving the fuel lines = around behind=20 the firewall may have allowed fuel to flow in a wired way and it drained = into=20 the cabin.....not sure, but first things first, lets clean the fuel=20 up......anyone got a cigarette???? <g>
