Ercoupe 415 accident near South Boston, Virginia, December 6, 2020
On December 6, 2020 at about 9:18 pm local time, a 1946 Ercoupe 415, registered N2674H, was substantially damaged in an accident during enroute near South Boston, Virginia. It was a personal flight under general aviation rules (Part 91). No one was hurt; 1 person was on board or involved. The weather was visual conditions (good weather).
The NTSB's probable cause their words, unchanged
The improper installation of a fuel filter screen cover gasket, which resulted in its failure, fuel starvation, and a subsequent total loss of engine power during cruise flight. Contributing to the accident was the unapproved fuel sight gauge, which obscured the pilot’s view of the fuel level in the fuel header tank.

The NTSB's narrative final · quoted from the NTSB record
During cruise flight, the engine lost total power and the pilot performed a forced landing to a road, during which the right wing sustained substantial damage. Subsequent examination of the engine revealed the failure of a fuel filter screen cover gasket from the fuel transfer pump, which transferred fuel from the wings to the header fuel tank. The failure allowed the fuel transfer pump to draw in air rather than fuel. Given this information, it is likely the engine consumed all the fuel in the fuel header tank, and the fuel was not replaced with fuel in the wings due to the transfer pump anomaly. When the failed gasket was replaced with a new gasket, the engine started normally, and the fuel transfer pump operated normally. Further examination of the failed gasket revealed that the gasket was damaged, likely during installation at the most recent annual inspection about 4 months before the accident. Additionally, the sight gauge for the fuel header tank was cloudy and was an unapproved part, which obscured viewing of the fuel level in the fuel header tank and likely prevented the pilot from recognizing that the fuel was not transferring properly from the wing tanks.
