What is the consensus on replacing fuel shut off valves: stick with a brand name like Briggs, Stens, etc , or any generic off Amazon with decent ratings? I did see a rather nice metal one, but at about three times the price of the plastic it made me reconsider.
The main point is that they have to withstand fuel. A raw brass needle like used on air tanks may leak around the stem where the seal is. Fuel will swell and degrade soft rubber product, so Viton synthetic rubber is used.
