Disclosed is a fuel pump system (100) and an associated method for delivering fuel from an associated fluid source (112) to an associated use (102, 104) downstream, including (i) start mode, (ii) operating mode and (iii) actuation mode Engine. The system has a pump (110) including a primary stage (116) having an inlet (114) and an outlet (120) configured to selectively provide pressurized flow for the (ii) mode of operation, and a Regenerative stage (130) jointly driven with the primary stage to selectively provide pressurized fluid for (i) start mode and (iii) actuation mode.
