ABSTRACT:
A multi-stage automotive fuel pump includes a casing and motor located within the casing for driving primary and secondary pumping sections, with the primary and secondary pumping sections sharing a common wall which axially separates primary and secondary rotary pumping elements and which houses a fuel transfer for moving fuel from the primary into the secondary pumping sections in a manner which avoids generation of turbulence and cavitation.
