Need help determining fuel filter fitting size.

[Samckitt]

I need to replace the fuel line on an 86 Monte. First thought was to replace it with repro Buick Grand National fuel line. It has the provision for the fuel filter & since the Monte now is fuel injected I figured it would work perfectly. Well the fuel feed line is $100 plus $40 to ship it. That is crazy. So I was going to make my own, but I can't find anyone to make the flared O ringed fitting needed for the filter. I had a brain fart & thought about a couple fittings I had for a TPI swap I did a while back. Turns out the AN to O ring fitting for the TPI fuel lines screws into the filter, & is a -6 AN on the other end. BUT, (always a but isn't there?), I don't think the O ringed end is the proper size. Feels like the O ring goes in too far into the filter.

Anyone know what size & name is for this O ring fitting? Are they called Saginaw fittings?



Thanks
