Claim:
A re-fueling station for selectively dispensing fuel in the form of liquefied gas or compressed gas, said re-fueling station comprising: (a) a storage tank within which liquefied gas may be stored; (b) a dispensing system comprising: a first dispenser for dispensing compressed gas; a second dispenser for dispensing liquefied gas; a heat exchanger operable to transfer heat to the fuel; a flow diverter operable to receive fuel through an inlet and selectively direct fuel through one of a first outlet or a second outlet; conduits through which fuel may flow from said first outlet to said heat exchanger and then to said first dispenser, or from said second outlet to said second dispenser; and (c) a positive displacement fuel pump operable to draw fuel from said storage tank and discharge fuel to said inlet of said flow diverter, wherein said pump is selectively operable in: a low speed mode when fuel flow is directed to said first dispenser to deliver compressed gas; and a high speed mode when fuel flow is directed to said second dispenser to deliver liquefied gas, whereby said fuel pump operates with a higher number of cycles per minute compared to when said fuel pump is operated in said low speed mode.
