Been there, done that.
Fortunately, I got "stuck" in a populated backwater system and managed to refuel and buy a poxy 3E fuel-scoop which made the rest of my journey tortuously slow-going - something which ensured I learned my lesson.
Urgh, that must have been painful...likely a better lesson that having to call for assistance lol.
By the way, is calling the Fuel Rats something that can be done in-game, or is it something one does outside of the game? I guess if you have one in your friends list it's all in-game, but I was wondering how it works if not.
Scoob.
