You can also use Earl's part number 165056ERL, it converts 5/16" hardline to -6an.

Nice find Chris. Use a legit tube cutter and there will be no flaring necessary, right?

Correct. There's a small piece inside the two halves that essentially flares and seals the stock line as you tighten it. I just noticed these are only rated up to 50psi though, not sure how much a regular 37° flare fitting is rated to but you might run into issues if you run over 4 bar fuel pressure.

Hmm 50psi rating would be pushing it - especially if you're boosting 20+ psi.

Regular flare fittings are the same fittings used in hydraulics - aka 3000+ psi lol. Of course at that point the hose limits that.

Hmm, also the 50 psi rating might be a safety factor of 2 or more. Might still be okay but I would want to verify with the manufacturer. There could be a similar option by another vendor that can handle the pressure comfortably.

Yeah, I'm sure there's a factor of safety in the 50 psi limit, I wonder what it is. If I get bored I might give Earl's a call and see why the rating is so low and if it's ok to be over 50psi as long as it's not continuous.

That is a compression style fitting. The exact fitting the OP suggested against using in his post. You can go that route, but I would never trust a compression fitting to my main fuel line feed.

Yeah, after reading about compression fittings I'm going to return them to Summit and go with the flare fittings.

The more I read about the compression/slip on fittings, the more I'm scared of them!

The last thing you want is atomized fuel spraying out in a hot engine bay from a high pressure leak. No thanks. I'll do it the right way and use flared tubing with the tube nut. No way I'm risking my engine bay at just the minimum to save some effort up front!
