I certainly owe ya a small prize!
I learned there is a lot more to a fuel system than just a filler cap and an outlet to the engine.
Design of vent line to run down below the tank to prevent fuel running out if upside down.
Return line raised above the high fuel level for constant head to keep accurate fuel consumption readings.
What I am still confused about is the dwgs for the newer vent line attachment show a plastic "t" line at the top of the vent tube, with 2 lines running to the bottom of the fuselage. Is that some kind of anti siphon system ?.
