It sounds like there is a problem with the connector on the fuel pump. So you could fix it with a new pump or you might be able to just skip the connector by adding a crimp connector for the broke pin.

The tank is held in by like 4 14 mm (15?) bolts. I didn't undo the lines as I had already cut the lines running from the front to back of the car. The filler neck has 2 connections. A vent and the larger filler neck hose. A pick or small screwdriver is very useful to get stuck hoses off. I didn't bother and just cut the hose (scrapping the car). Unplug the fuel pump from the car. Then the 6 bolts that hold the fuel pump sender in.

Hopefully that helped. I didn't look through all the links you posted.
