I think my fuel floats are shot…left tank is fine…the right is dead flat….do these get rebuilt or replaced….don't want to go electronic….have a fuel totalizer so I have accuracy but want the individual tanks to be readable….is there an improvement to shellac coated corks…or are we required to relive 1956…..

Good chance the magnet has lost strength, I've read they can be remagnetized but haven't attempted myself nor sent out to a shop that could.
We had a dead gauge on our 54, ended up just replacing it with a new rochester

New one is readable for sure - but per my definition I'm not sure I'd say it "works." I'm a stickler on dipping the tanks every flight.
Eventually we'll replace some/all of the panel in this plane, and will go CEIS at that point.

Agree re dipping…as the only pilot and the one who does the refueling this is something I control…I carry a dip stick so I can prove I have a way to measure the tank amount…would like the electronic system…but lower in Improvement Stack…thanks for lead on new floats…that’s what I think I’ll do….
