A vehicle including a pressurized liquid fuel system includes a first pressurized liquid fuel tank arrangement, a second pressurized liquid feel tank arrangement, and a balancing conduit open to a first fuel tank and to a second fuel tank at least one of above a maximum liquid level of the first fuel tank and a maximum liquid level of the second fuel tank and below a minimum liquid level of the first fuel tank and a minimum liquid level of the second fuel tank. A first return line and a second return Sine to the first and second fuel tanks are configured such that a pressure drop across the first, return line from a pressurized liquid fuel circulation system to the first fuel tank is adapted to be the same as a pressure drop across the second return line from the pressurized liquid fuel circulation system to the second fuel tank. Methods for operating a pressurized liquid fuel system are also disclosed.
