Lil hose between tank sender and hard line cracks over decades. Did you try another coil? We could toss everything in the book but that could send you on a goose chase.
All fuel line hoses have been replaced. Coil would not be the issue if the car ran from another source of gasoline. Car ran both times i tried it with an external pump once pulling gas from a jar and the second time pulling gas directly from the line to the tank. Hook the line back to the cars fuel pump issues again. This has to be a fuel delivery issue. Only issue is both pumps were brand new.
