The manufacturers of PTFE tape (teflon) say 1-1.2 wraps on new threads, 2-1/2 wraps on old threads.

But at least one of them I know of forbids using teflon tape on the hydraulic systems used on the machines that make the tape.
The problem is, if the connection is ever taken apart and re-assembled there's a good chance small pieces of the tape can end up in the hydraulic system and clog a valve or orifice.


Assuming it's wrapped in the correct direction, 2 to 2-1/2 wraps should do the trick as long as the threads aren't buggered all to heck.
I can't tell from the picture but if that filter housing is plastic, over-tightening it could cause leaks.
I would recommend using a teflon paste-type pipe dope instead of tape.
But the best (low temperature) pipe dope I've ever used is green key-tite.
