Not sure how that can happen in any vehicle unless you have cut up / bare wiring down to that connection point as there's plenty of room between where that sending unit mounts and the firewall. My engine bay is clean and all wiring is tied up and enclosed/routed in wire loom. As described in my initial post it appears these AC Delco units do work at first but then fail at some point. Probably a cheap ass spring internally being used that doesn't have the rigidity in it like they used to make and fails.
