Hello all, I'm wondering if any of you know of a fitting adapter that just screws on to a hard fuel line nut, instead of cutting the line for a compression fit AN adapter? I'm upgrading my built 283 to multi-port EFI this winter. The plan is to replace the smaller fuel line with two Shafer's Cl***ic 3/8 feed and return hard lines to stay NHRA legal, with the last foot as -6 AN PTFE going into a fuel pressure regulator, then to the Pro Flo 4 fuel rail. I've never run fuel line before, so the idea of a cutting a hard line and fitting a compression fit adapter is making me nervous, but maybe it shouldn't? I already have some Earl's hard line to -6 AN compression adapter fittings in my cart, but am wondering: does an adapter exist with a female 3/8 thread on one end, and male -6 AN on the other, that the hard line nut would just screw into? Thank you for your advice.
Yes there is , But , 3/8s "" Thread"" to 6 male? Or 3/8 OD hard line ? to 6 male ? & or Inverted ? The web site with pic above Is NPT to Male #6 AN /Jic Many options brands Parker Aeroquip Earls Red Horse Vibrant Ext Stay away from cheap knock off china Fittings Aluminum, steel or br***
this? https://summitracing.com/parts/fra-491940-bl they have other genders too, but I think this is what you described
Oh wow thank you all for these. Had no idea there were options like this. 19Eddy30 I need to call Shafer's this week to verify the nut thread type but it's on a standard 3/8 OD fuel line. Will keep you all posted, and thanks again.
Oh, I got the wrong part, I was thinking 283, not 3/8" you might want to look at this one https://www.summitracing.com/parts/fra-491942-bl

Gotcha, thanks. Did I mention that I've been tuning the hell out of my Edelbrock AVS2's rods and jets lately?
Another option is to take a -6 AN (or JIS) union, cut one of the ******s off and drill to 3/8". Silver solder the tube into the fitting. The first couple of these I did I took to my local hydraulic shop to have done, but finally just asked if I could buy a stick of silver solder and did it myself. I don't trust any adapter with orings in it. 37 degree or inverted flare is ok but still with the potential to leak
