Maverick Hybrid does have an in tank fuel pump. Since the Hybrid is NOT direct injection it runs a pressure of probably 58 psi. Which is the pressure most port style fuel injectors operate at. There is no need for an additional engine mounted fuel pump like a direct injection engine requires. While most new Fords do not have a return fuel system, due to how the Hybrid is set up...it might and that would explain the pressure in the fuel tank.
