Not sure if this would work but you could try to make a 'special' radial coupler with a top node on the side and put a bottom node at the side of your bomb model. Only allow stacking in the bomb config so IF someone tries to use the bomb without the coupler he would have to put it sideways on the top of his rocket and this would not be very usefull. Just a thought..

Thank you all but this does not exactly solve my problem. I want to make the fuel flow through the Attach-nodes like this: [xx][xx] [xx][xx] -fuel tanks [xx][xx] [xx][xx] [ ] /\ -engine so the engine under the left fuel tank also consumes the fuel of the right fuel tank

Hi I want to design a new fuel tank and it would be usefull to know if the top-down fuel 'flow' is hard coded or if its changeable by any value I havnt found yet
