How do I transfer fuel from one vessel to another

[Jeb federation]

So I sent a mighty ship out to sea, only it ran out of fuel 3/4 of way to its destination. So I built another ship to refuel the first vessel. I successfully docked only to find out that I no idea how to transfer the fuel. Could someone tell me how to do it?

They're already docked? Good.

Right click a tank that has fuel, then alt + right click a tank you want to transfer fuel to. By alt+right clicking, you open a part menu without closing the ones already open (or, you can click the little icon on the top-right of the widow, and it will stay open).

With more than one tank's menu open, just click the "In/Out" buttons, and off the fuel (or any resource, really) goes!

OK thanks!

Note: in career mode you have to upgrade a building first. I don't remember which one, R&D?

Oh, yes, I forget! That is correct, your R&D building must be at least of level 2.

The alternate way to handle it is by pinning windows open, rather than using Alt (mod). But yeah, the point is that you need to have the context menu of a fuel tank on the tanker ship open at the same time as the context menus of the empty tanks of the recipient ship.

I'm Interested in seeing your ship and the refuel-er!
