These sections are provided with flanges la and lo and are attached in any suitable manner 'as with which is fitted into the upper housing section I. himp casing members 4 and I are provided with central openings II and i6, respectively, through which passes the rotor I. Opening II also provides a central fuel intake to the volute member 4.

Motor brush structure is generally indicated at ll being supported in the lower housing section 2. A pump discharge passage is indicated at II which communicates with the groove 4.
In operation, fuel enters the inlet ports I! and flows into the spaces between the impeller blades as indicated by the arrows from whence it is thrown by centrifugalforce into the volute groove 4 and thence out. throughthe discharge screws (not shown). Fitted into the upper end of the lower section I is a pump'easing comprising a disk-like member 8 having a volute groove I formed therein and a disk-like cover member I. Journalled in the housing structure at i and 'I I is a vertical rotor generally indicated at l which comprises a shaft 0, a motor armature II, a pump impeller II, and a commutator it.
