Gas lines and how to side mount those donut shaped fuel cells

How are people side mounting those fuel cells and getting the game to consistently have the fuel line actually connected to the main trunk of the craft.

sometimes it works sometimes it doesn't and there doesn't seem to be a way to make it work right 100% of the time. sometimes in the VAB it says it's hooked up, sometimes I goto launch and it stays hooked up. Othertimes not. How do you guys make it work for your landers?

Radial mounting the toroidal tanks is done by placing a cubic octagonal strut (in the structure section) first and then attaching the tank to that. This is actually a really handy technique in a lot of other situations, too.

You shouldn't need fuel lines then, fuel will automatically flow to the center stack.

could you show some pics??

No it won't. It could flow from parent to child but not the other way. I.e. from central tank to the toroid yes, from toroid to central tank no.

Pick a cubic octagonal strut (that little girder) and move it on the side of the tank. Press W twice and it will turn inside, leaving just its bottom attach point sticking out. Then you can attach the tank to that point. Note that it might be hard to get the strut out of there, you may need to clip your camera inside the tank to do that.

Pictures would probably help here.

Ack, I always get that mixed up, mostly because I'm usually trying to feed radial engines from the center stack rather than vice versa. Thanks for the correction.
