Re: Flame arrestor?
It works on the same principle as the miners Davey lamp, invented by Humphry Davy. The metal gauze conducts the heat of any external flame or spark away so that the fuel on the inside of the arrestor cannot heat up and ignite. The Davy Lamp worked in reverse, preventing the burning wick inside the lamp's mesh screen from igniting the methane "fire damp" gas outside in the coal mine.
That's what I think. And why I use rhem. I do remove it while filling the tank because it impedes flow. I replace it before driving away, in case of a collision or carburettor fire etc.
Any other opinions?
