A system for pump assist to maximize fuel consumption in a natural gas powertrain includes a fuel delivery system including a natural gas storage tank supplying a first natural gas flow, a pressure sensor disposed to provide data regarding a natural gas pressure within the storage tank, and a natural gas pump operable to selectively boost the first natural gas flow to create a second natural gas flow with increased pressure. The system further includes an engine operable to utilize one of the natural gas flows to provide an output torque and including a fuel injector and a computerized fuel system controller programmed to monitor the data regarding the natural gas pressure within the storage tank, compare the data regarding the natural gas pressure within the storage tank to a threshold cut-off pressure for the fuel injector, and command activation of the natural gas pump based upon the comparing.

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.
