摘要： A fuel return system for returning fuel from a fuel pump to first and second fuel tanks in an automotive vehicle includes an open T fitting having branches connected through couplings to the first and second fuel tanks. The couplings each have a low return, fuel flow orifice which is continually open and a high return, fuel flow orifice which is normally closed by a valve. The low pass through orifices prevent one tank from receiving extra fuel during idle and allow the first and second fuel tanks to siphon to the same fuel level when the vehicle is parked. The high flow through orifices open to prevent return fuel back pressure to the engine and have a cracking pressure responsive to the engine running at a level higher than idle.
