Fitting needed to use braided fuel line

Stock stuff is usually inverted flare. So it's either going to be the 5/8-18 posted above or the 1/2-20 like this:

My friend's car when we set it up we used the above. The thread is the same as a wheel stud for a large bolt pattern mopar if that helps you match it up. An elbow fitting would have to have a swivel after the fitting to seal because the fitting needs to deform it and the cone at the bottom slightly to seal. My opinion the best bet is to either use a straight fitting and a 90 degree hose end or an intermediate swivel fitting.
