I can not get an Ion engine to 'click' to bottom of xe-100s fuel tank, what am I doing wrong??

Did you try holding Alt key while attaching? It should snap the piece to the node.

Also, check if orientation of the engine is correct.

Edit: I can't find a tank with that name in stock game. Could it be something from a mod? 

Forgot to mention before, check if the node shows up on the tank while you're dragging the engine. If not, then either the tank doesn't have one, or it might be taken by another part.

^ Yes, this.

@Lohan2008, here are the xenon tanks that are part of the stock game:

The PB-x50R is radial and can't be attached to, but either of the "stack" tanks (PB-X150, PB-X750) ought to work fine.
