what do you need to transfer fuel?

I'm starting in the game, and I don't know how to transfer fuel. I've already tried selecting a tank and then another tank, but the transfer option doesn't appear.

Welcome to the forum @maverick2077, your thread has been moved from tutorials to gameplay questions.

If you are playing a career game you need to upgrade R and D one level before you can transfer fuel. Once that is done you right click on one tank and then hold alt and right click other tanks and you should see in/out propellant pumping options in the context window.

The first R&D upgrade unlocks “resource transfer”, that’s what you need to transfer resources between parts.
