Photos show there is no slack on the compression fitting to allow me to get any ptfe tape on.
Because it's not possible to move the compression nut back so that it exposes the olive.
What can I do?
kez, you shouldn't need to use any tape on it, hence @ianmcd 's question. If it won't stop dripping though then the little of the olive you can see in 1st pic, cover in a couple if wraps of tape, that should be enough.
