The weight of the fuel in the tank will exert less pressure on the pump housing than a return line that enters the top of the tank. The pressure is determined by the height of the fuel level above the pump. The amount of surface area of the fuel in the tank will not affect the pressure in the line. A fuel return line going to the top of the tank will always be filled to the uppermost part of the line. A fuel line returning to the bottom of the tank will have a pressure dependent on the level of fuel in the tank. A check valve in the lower tank fitting can increase the running pressure of the pump.
The pump should be sealed to hold the pressure the charge pump develops, somewhere around 60 PSI. I would look for wear in the pilot tube where the seals ride. If the tube has been replaced and not installed with the correct sealant it is possible that the fuel can leak between the pilot tube and pump housing.
