The teflon tape just goes on the threads to help prevent leakage from the WIF sensor since they are plastic threads. I am not sure which O-ring you are talking about, all the O-rings should come with your new filter and should be replaced with filter, 1 for the WIF sensor to fuel filter surface(small O-ring), and 1 for the fuel filter to fuel filter housing surface(Large O-ring). If that isnt what your looking for than please be more specific and I will try to help you out.
