ABSTRACT:
A dual fuel pump fuel extraction system for saddle fuel tanks. A primary modular reservoir assembly (MRA) includes an electric primary fuel pump located in the primary sump of a saddle fuel tank and a secondary MRA including an electric secondary fuel pump located in the secondary sump of the saddle fuel tank, wherein both the primary and secondary fuel pumps extract fuel from the primary sump and simultaneously transfer fuel between the primary and secondary sumps so as to thereby ensure both the primary and secondary fuel pumps have fuel, without starving one before the other, until fuel becomes depleted from the saddle fuel tank.
