******Doesn't it have a float on a wire? Not the same******

Exactly the same.You really should go have a look. No wire. Just a sight
gauge with a red colored cork floating. I spent my pilot youth ferrying
these fine airplanes from Lock Haven to Washington. Oregon, Alaska.

The float on a wire is on a J3, Taylorcraft, Aeronca, usually on a forward
fuselage tank. Super Cub tanks are in the wings.
