A filler neck for a fuel tank used on busses achieves higher filling rates by varying the geometry and cross sectional size of the filler neck depending on local slope of the neck and available space to fit the neck, particularly between a bus chassis frame rail and the bus body floor.

Filler neck for motor vehicle fuel tank

Each of two fuel tanks is disposed at a respective side of a chassis of a motor vehicle and has a respective sender for indicating the level of liquid fuel in the respective tank. A pump draws fuel from the tanks through a respective fuel draw conduit. Excess fuel is returned to each tank through a respective fuel return conduit. When the senders indicate an imbalance of fuel between the two tanks, a valve mechanism controlled by the senders disallows return fuel flow to the tank whose sender indicates that the level of fuel is greater than that indicated by the sender of the other tank by some defined amount while the pump continues to draw fuel from both tanks through the fuel draw conduits.
