Yes, it's a bit of a specific topic, but can anybody tell me if the Type F-2 fuel selector is the same as the Type F-1 except for the size of the ports? I'm working on a 1928 Travel Air that had an F-2 installed at some point, probably when it was a duster, but it now has internal leaks due to a scored cork cone. The F-2s seem to be unavailable, but the F-1s are out there NOS, and look the same except for minor details like possibly the ports being one size smaller NPT. Not having one to hand I can't tell, but maybe somebody out there knows. Anybody know what types of aircraft used the F-2? It has four positions, one-two-off-off.

Here are some F-1 photos from the net-

Would be heavily dependent on what engine is installed. The F-1's were for engines like the O-435 and smaller. It might not flow enough fuel to keep something bigger fed at max power, worst case scenario.
