My fuel tank sits in the console - I must admit I never like the idea of it venting petrol vapour into what is an enclosed area with wires and battery in there and then me sitting on it!
I have just upgraded my tank to a larger one with an external filler mounted into the side of the consol and tank vent - All that can go wrong now is my plumbing
but I will make sure I check it, just by lifting the seat everytime i fill up.
After seeing a petrol boat on the Thames blowup (after filling with fuel) blasting people and children into the water and burning them just as it left the petrol pontoon I am always careful when filling up boats -
in the case of the boat on the thames, a fuel pipe had come undone (through age and perished) and poured all the fuel they had just taken onboard into the engine bay - it took a minute or two after they had started it for it to ignite though...
