Donald, Ah, you've learned the right lesson from that fogged wire gauge tube! Indeed, it is the nose tank float gauge that must be watched even if you never look at the wing tank fuel levels. (And, yes, knowing the status of all tanks is minimal smart piloting - I'm not saying to ignore the wing tanks.)
Did you, perchance, have auto fuel in the plane's tanks? As auto fuel doesn't have any die, it could, I would guess, leak out one drop every few seconds and empty the tank over a several week period. If it were auto fuel, there'd be no stain to betray the leak. If the leak were slow enough and the hangar has some ventilation, you could well not have any fuel smell. With aviation fuel, leaking through the carburetor tends to leave a stain and it's usually pretty apparent unless you have a dark dirt hangar floor.
