You only need teflon tape/paste on the pipe thread fittings (like the fuel pressure sending unit)...the FAST rails use o-ring boss fittings, so if those are leaking, replace the o-rings. If the braided line itself is leaking, it was assembled incorrectly, and if the AN fittings are leaking, you either have a damaged 37* face that can be fixed by getting some SECO 37* conical seals or replacing the fitting outright. Teflon tape/paste on an AN fitting is a no-no - it won't seal anything, and could end up in your fuel injectors if you use too much.
