Could you please see if these two together will seal? The Fuel lines and quick connect fittings say '-6 AN' fittings. This is all new to me, so I'm not sure if these two will mate together properly? I'm just trying to be safe and not mess this up by being extra careful.Never use ptfe or Teflon tape in fuel applications. AN fittings are a flare type fixture and seal based on proper application of torque.
Okay thanks. When looking at the female connection point I expected to see like a 63* angle on the fitting - so they would match, bit just looks flat inside so that made me a little nervous about how it would seal. I'll give it all a try tonight.yes, part of the "AN" standard is the 37* flare fitting. You should be good to go as is
