A moulded plastic tank is disclosed to comprise a plastic tank wall (15) and an externally flanged, closed-section conduit (20) at least partially embedded in the wall (15). A method aspect of the invention for making certain embodiments of such moulded plastic tank comprises the steps of: (A) forming a molten plastic parison; (B) locating an externally flanged conduit between the parison and a moulding cavity surface; (C) closing the mould around the parison; (D) introducing fluid pressure into the parison to expand it outwardly against the cavity surface and at least partially envelop the flanges of the conduit; and (E) removing the finished plastic tank.
