Abstract
A fuel feeding apparatus is provided with a cap body for closing an opening of the tank, and a liquid level detector that is attached to the cap body and detects a liquid level of the fuel. The liquid level detector includes a floating unit immersed in the fuel and a strain gauge embedded in the floating unit in proximity to the cap body to detect a compression stress caused by buoyant force of the floating unit.
