The filler member comprises a first fuel inlet pipe (4) which can put a fuel filler inlet opening (2) into communication with a fuel tank (3) of the vehicle. The member includes a second breather pipe (5) instaled within the first pipe and operable to convey air present in tank towards the fuel filler inlet. The first pipe is coupled to the tank via a friction bit enlargement and a sleeve (22) urged against the pipe by springs (23). - At the inlet end, the first pipe is retained by an annular swelling (32) engaging within an annular cavity (33). The vent pipe is held at the outlet end by a grra grating (44) and snap teeth (52). The grating also prevents the insertion of a rogue tube for back-syphoning. The corrugated portions of the pipes are snap-fitted to the relevant straight portions.

(9pp Dwg.No.2/9) - GB2182999 B A fuel filler member for vehicles, comprising a first fuel filler pipe operable to put a fuel filler inlet into communication with a fuel tank of the vehicle, a second, breather pipe installed within the interior of the said first pipe and operable to convey the air present in the said tank towards the said fuel filler inlet, said first pipe having a first end portion engaged internally by an annular portion of the said fuel filler inlet and a second end portion internally engaged by a first sleeve in communication with the said tank by means of a second sleeve extending from this and internally engaged by the said first sleeve; first and second fixing and orientation means being provided between the said annular portion of the said fuel filler inlet and the said first end portion of the said first pipe and between the said first sleeve and the said second end portion of the said first pipe. USAB- US4718568 A A vehicle fuel tank fuel filler is disposed between and connects an inlet and the tank. It comprises a first fuel filler pipe, and a second breather pipe located in the first pipe. The first and second pipes define between them a passageway permitting fluid communication between the inlet and tank. - The second pipe is dimensioned to convey air present in the - tank towards the inlet, is in major part rectilinear and is shorter than the longitudinal extent of the first pipe. The second pipe includes a second pipe central portion having a corrugated outer surface.
