That's why you mount the pump near the bottom of the tank.
The fuel level will always be above the pump.

so if the pump is below or at the bottom of the tank, does the portion of fuel in the line coming out of the tank drop back into the tank?
my point is the fluid doesn't know where the pump is, as long as there is no air leak, the siphon is maintained.
