We are talking about wooden airframes, you can't get an electrical connection to wood. But the question I asked was is the metal engine bonded to the metal fuel tank ? Other than by dubious, sometimes plastic pipe work.
I do know from personal experience (because I removed it) that the rear tank on my Emeraude fitted behind the seat was not bonded to the engine/firewall or anything metal attached to them. To remove the tank I only had to remove the plywood shelf, disconnect the rubber feed pipe, remove the filler cap, disconnect the gauge wiring and lift it out.
The only bond that may have been possible would be the sender unit wiring, but the gauge sender is fitted with a rubber seal. All a bit dubious I thought.
