AN Fitting Question

I bought 4 of them from Evil Energy but haven't run them on a vehicle yet. I did connect them to some brand new hard line to do a low/med pressure leak test and they worked just fine. I possess many of their products and it all looks exceptional to me, and with their stuff right next to some from Russell or Earl's you can't tell them apart. I've got their AN, NPT, ORB, straights/ elbows, swivel fittings, hose, and 58 mm filter. The swivels all move freely, not one single fitting had a burr, chip, or defect in the threads- internal or external. All pieces thread together and disassemble with ease. The anodized finish looks very even and uniform, as well as completely thorough. I haven't found a single problem with anything I've purchased from them. And yes, ferrule fitting connections require a clean and dirt/rust free connection or any brand will leak all day.

Something to keep in mind a lot of those type of fittings are designed to use that ferrule on aluminum tube as it's easy it to become one.im running this on my stainless hard line to AN hose/feed my mechanical fuel pump.

I believe so due to the fact that compressing into my stainless line is much harder than your oe carbon steel line.. Another option would be to use a tube nut and coupler assembly that requires you to make only a single 37 degree flare on the steel line,that mates to a male an fitting coming from your fuel pump hose side.

here's that tube nut/coupler in action mikester very straightforward

If thats the one with the flare is there a specific brand that you used ?

yes this's the one I spoke of that requires a single flare,I got mine through a Pharmaceutical pipe fitter.its a swagelok brand,they make killer stuff.
I wish I had a part# reference for you of some kind but I don’t.this's the same part by a different company.

i think that ferrule would work,it did on my stainless hardline.Honestly for me it boils down to what is gonna be easier to install-say if the body is still on the frame &you're doing it on the ground,cutting& flaring is more cumbersome than the slip on compression version.
