I love to look of this valve. I have an issue with the NPT not threading all the way flush with the tank but that is not an issue caused by the valve itself but by non-metric tanks insisting on using NPT. I plan to buy a tap set to cut the bung so that the fuel valve will sit where I want it to. The only improvement that I would like to see is a positive stop on the switch so that you know for sure its closed. Down is off but if you turn it left or right it's open, could be confusing if your forgetful like me.
