OP, hook up a mechanical gauge and confirm oil pressure. You'll need to troubleshoot the fuel issue separately.

You are only part correct. IF you have a three wire oil pressure sensor, the center wire goes straight to the dash that is correct. But there 2 more wires, this circuit has to be closed to keep the fuel pump operating. it is as you say a safety issue, but for roll over or flip up on the side protection. When the oil can’t get to the pickup, a lot of fires were started because of the motor not shutting down. Generally if you lose oil pressure the motor Is toast anyway, at least all of mine were gone
