Can't get my Barrel work

[Friendlyx]

I successfully added parking positions for the barrel and also couplings but can't get the Docking Arm to work.

First for the couplings they work but they still keep on working with the hose disconnected even when far far away from refill trailer. It only stops If I disconnect both ends of the hose.

And for the Docking Arm, I don't know I tried everything from the tutorials but no help.

even with debug nothing found for the Arm. There is no Node/collision created.

finally found the error. Fillarm was added under the Pump syntax
