Nothing at all on A/N flair fittings; the flare should do the sealing. 
Teflon tape is considered bad news for anything oil or fuel related; it 
can shed pieces that will clog small passages. Teflon paste type sealant 
is fine for oil. Fuel Lube (brand name) should work for NPT fuel 
fittings; there's another product that's much easier to find (any good 
plumbing supply) but I've forgotten the name. I'll find my can next trip 
to the hangar.
