All ships get a minimal fuel processor built into their fuel tanks. You can install a much larger one as a ship system which will allow ships to refuel much faster. In practice the only ships that usually have the larger fuel processor are deep scouts which routinely travel through uninhabited systems or fuel tenders which scoop gas giants to process the raw hydrogen then sell the refined fuel to ships passing through the system.

We have a espionage campaign you see...
Not by the rules. If you want to design a ship that can go Jump-4 or Jump-5 you need to install a J-4 or J-5 stardrive* and supply it with fuel tanks that take up 40% or 50% of it's volume. By the RAW of the setting there is no alternate fuel source that allows you to jump for less fuel than the 10% of ship volume per parsec (though the creation of such a drive might be a good plot point in an adventure, and would be highly sought after by EVERYBODY, who would be tripping over each other trying get their hands on such an innovation).

Theoretically a ship could have, say, 20% of it's volume in internal tanks and 20% in external drop tanks, giving it the capability to jump 2 parsecs on internal fuel or 4 parsecs if it has drop tanks. But that's a design decision that would need to be made when the ship is created; most ships just rely on internal fuel tanks and have just enough internal fuel to make one jump of whatever their maximum distance is.

* Note that a Scout has only a J-2 stardrive installed, so even if you somehow fed it more fuel it can't jump more than 2 parsecs without replacing the stardrive with a much more expensive one.
