Henry (and others),
I came across some repro fuel senders (Jaeger and Veglia) for the Lancia Appia, sold by
Cavallito in Turin. You might be familiar with these already, but the upper part of the unit looks almost identical to the 2600 fuel sender, with the exception of the pivot rod mechanism and the location of the electrical terminals. I wonder if it would be worth exploring further if this sender could be adapted?
No connection, just passing it on.
