Patent ID: 7185636

Claim:
A fuel delivery pipe, in which a fuel inlet pipe connected to a fuel delivery body as a returnless type having an injection nozzle but not having a return circuit connecting to a fuel tank is coupled to the fuel tank through an underfloor pipe arrangement, wherein: a cross section shape of said fuel delivery body in a perpendicular direction to an axis of the fuel delivery pipe is formed in a substantially rectangular shape; first two wall surfaces at long sides of the substantially rectangular shape are respectively bent inwardly as formed in a double side concave shape; second two wall surfaces at short sides of the substantially rectangular shape are respectively flat; a socket for connecting each injection nozzle is secured to either of said first two wall surfaces or either of said second two wall surfaces; and flexible absorbing wall surfaces are furnished by said first two wall surfaces to absorb pulsation by deformation upon receiving pressure in association with fuel injection.
