Make all decouplers not cross-feed fuel

[Mr_Auto]

As the title say, i'm thinking about radial mounted decouplers, because if you use others like TR-18A Stack Decoupler the fuel is not flow, why not make this rule for all decouplers?

[stupid_chris]

All the decouplers already prevent fuel crossfeed?

Are you sure ?

That likely is because the game considers the grider to be attached to the fuel tank and not the decoupler. If you were to simply attach a fuel tank and an engine to this decoupler, fuel would not flow.

Anyway, what happens if you decouple this? This sounds like a bug in the already wacky fuel flow logic more than a problem with the decouplers.

You can cut the fuel flow by clicking on the fuel tank, and clicking on the little green triangle for both liquid fuel and oxidizer. That will keep the fuel tank from flowing fuel.

This is not helpfulness because i need quick change (detach arm and use fuel from this tank)

p.s this is not topic about problem but suggestion to change this in game/fix this

When i decouple this the whole arm is detaching

i'm sure i connect this to decoupler not directly to fuel tank

another screen:

I came up with new idea, add to all structural elements option so people will have choice if this element is cross-feed fuel or not, this also can be useful

I think you have a bug here. The first image you showed us, is basically a simple way to transform a normal engine into a radial engine, like the white one in the second image. Radial engines are capable of pumping fuel "sideways", since they're on the side of the fuel tank, and it seems that radial engines pump through decouplers, which they shouldn't.

It's worth making a post in the bug/support forum to show this off, that shouldn't be happening.

It's not bug, when you see the discription in game you can see information that the part is "Fuel Crossfeed Capable"

Bug is that EAS-4 Strut Connector has this information too but it's not fuel cross-feed,

or that the Structural Pylon has no icon in phases

p.s funny thing with this is that if you connect not only engine but also fuel tank to decoupler, engine will use only fuel from the connected fuel tank

You can go to the part config files and disable fuel crossfeed.
