40 years ago I'd agree, gas fumes were pretty volatile. We used to light fires and use a little gas as an accelerant out in the bush piles. And yes, throwing a lit match would have an explosion before the match hit the ground. Today's gas is not that bad. I weld and grind and have sparks all around the workshop where the Merc is parked. Never a problem. Not that I'm advising anybody else to do it but I'm comfortable with it. But yes, I do have intentions of getting a "real gas tank" back in the Merc.
