I'll have to see what I can do,
I don't have any cargo bays so I might have to dump equipment.
It's not the fuel I'm short of it's the jump range.
So let me get this right. You somehow managed to GET to New Yembo, refitted your ship with some extra gizmo's, and now you find the ship won't give you the jump range you need to make it across some/several of the spaces between stars?
On your Galaxy map is the option for Navigation set to ECONOMICAL ROUTES or FASTEST ROUTES? Economical will get you A LOT FURTHER that fastest overall, but relies on LOTS of short jumps being available.
If you still don't have the jump range, then you have to strip down your ship to the lightest possible to give you the ability to make longer jumps. DO away with any gear you really don't need just to get you back to inhabited systems..... if you make it! Remember, NPC interdictions will happen up to about 500ly away from any settled system, and I believe New Yembo is within this area! If it does happen, just submit, all pips to engines, and then BOOST, BOOST, BOOST and then SC away. Once in SC then go for the hyperjump. Using the FSD to jump up to SC is a lot quicker than going through the FSD charge to hyperjump.
Keep Hyperjumping - and scooping if you've bought a fuel scoop - until you get back to somewhere with a station you can dock at!
