Abstract
A fuel tank contains a swirl pot into which a fuel return pipe from the engine is directed and which induces fuel flow from the tank into the pot so that the fuel level in the pot is kept high. Fuel flow into the pot is induced by directing a flow of fuel from the return pipe over a ramp past an opening into the tank so as to create a low pressure area at the opening.
