"Ramscoop technology has been almost unchanged for centuries, because with nearly every system in human space settled there has not been a pressing need for ships to generate their own fuel. But with the Free Worlds war making travel once again more difficult, some engineers in the Deep recently invented a much-improved ramscoop for use in their merchant fleets."
You can buy this in the deeps outfit stations later in games campain. This will enable you to refuel far faster than the standard ramscoop by a deceant margin and is highly reccomended when you get jumpdrives due to the human nature of forgeting to look at the fuel gage while warping into areas with no ships and no refuel ports, where having it will become a life saver.
