A little silicone is fine. Just don't do what I did on an F4 and glue the snot out of it. You will never remove it without distroying the airframe.
Here is a good diagram for tanks that follows most setups:

Thanks for the reply, looking at the diagram, the main tanks feed the smaller tank, then to the UAT. My small tank is above the mains would this still work?
