I NEED HELP With Clamp-O-Tron Jr.s Fast!!!

[Isiac.T]

I have successfully docked onto my moon lander in a low orbit above the Mun for a refueling, since I am on career mode I only have access to the Clamp-O-Tron Jr. I attached an FL-T400 fuel tank to a clampotron and my Mod key+Right click is not pulling up the fuel exchange window! I have tried it with and without a adapter, and they have no effect. It shows that the ships have docked and become one, but no fuel transfer window. Help!

Have you upgraded your Research and Development building.
This is where you earn the ability to transfer resources.

^ This.   Thankfully you can do this 'research' while your docked vessel is in orbit and it will work without having to send new docking ports up.  

I assume by 'research' what they really mean is they finally found the missing manual page and have now figured out where the engineers put the crossfeed valves.

Yes very kerbal.

We can also rationalize this by assuming a bigger R&D can up load software patches to existing hardware in space. The very same software patch that provides the UI to pump fuel. Pumping fuel can be dodgy without an accurate flow monitoring system. Although your explanation is probably closer to the Kerbal truth.
