ABSTRACT:
A fuel feed apparatus including a sub-tank is received in a fuel tank having multiple tank sections. Multiple jet pumps respectively transfers fuel received in the tank sections into the sub-tank. Therefore, even if a fuel amount received in a single tank section decreases, fuel can be steadily supplied from another tank section. Intermediately pressurized fuel in a fuel pump is supplied to the jet pumps, so that fuel can be steadily supplied to the jet pumps regardless of fuel consumption amount in an engine. Fuel is drawn from an upstream side of a pressure regulator, and supplied to the jet pump. The pressure regulator has an urging unit, and controls fuel pressure without using a diaphragm. Therefore, the pressure regulator is simplified and downsized.
