But i can\t figure out how to do this  

Anyone that knows how to do this??? 

Can't seem to find anything that explain this.

Use a strut to connect the two parts.

The way KSP internally represents the craft means that craft cannot have "loops". Every part of a craft has exactly one "parent" (if you don't re-root then that's the part it was connected to when building the craft), and following the parents you get to the root part of the craft. (I computer science this kind of data structure is called a "tree".)
And, btw., the struts and the fuel-dutcs are actually more a variation of that theme than an exception. They "are" on one side and then point in a direction, saying "I connect to something in that direction".
