Abstract
A fuel hose should reduce noise during fuel injection into an engine, and should not interfere with other engine components. The fuel hose supplies fuel drawn up from a fuel tank to the fuel injection valves of the engine, and is formed from a resin material which is resistant to fuel. The fuel hose comprises a hose main body having a fuel passage, and an non-circular component formed as a result of at least part of the cross sectional shape of the hose main body being non-circular. The non-circular component has a plurality of ribs running in the axial direction along the hose main body, and absorbs pulsation by the varying of the cross sectional shape of the ribs in response to variations in the pressure on the fuel flowing through the fuel passage, thereby resisting alterations to the shape in the axial direction.
