Hose from Tank to Line 72

Obviously someone changed some stuff back here. It's not getting fuel, and this doesn't look right. There is no vapor port in the tank or sending unit, and I know that isn't correct because turning it over creates a huge vacuum in the tank unless the fuel cap is off. Is the end of the fuel line supposed to almost parallel to the ground and have a 90° bend that points to the front of the car? Or is it supposed to be angled down? It was built in Oct 71. Correct pics would help a lot! Thanks.
