Abstract
A vehicle fuel tank is provided with a pump mounted to the bottom of the tank. The outlet line leads from the pump in a curved path to a cover on the top wall of the tank. This arrangement facilitates assembly of the tank without difficulty relating to connection of the outlet line on account of variations in overall tank dimensions.
