I use those too... they can be great for that application. Or, you can buy them from Aircraft Spruce and pay a whole bunch more. How do I know?... I had a friend who years ago "introduced" A/S to these nice little "fuel" valves, selling many, many of them - indirectly from Ace Hardware, through him, to Spruce. I've had one on my Thorp for 27 years (direct from Ace).
