Fuel lines Hey guys, I'm curious to know how you adapt hard lines to flex line.
Just a flare, barb, compression fitting..? I had a recent leak at a couple of my connections and I'm curious to know your guys' solution or suggestions.

What style of flex line? Nylon lines require a special flare and a quick-connect fitting or a special nylon to steel compression fitting. Rubber hose requires nothing more than a slight barb/flare and some clamps.

I have rubber hose right now. I put a double flare on all my hard lines so they wouldn't be sharp and cut the inside of the hose, but it started leaking. I put a second hose clamp on for temporary fix.
I'm thinking of doing a compression fitting on the hard lines to -6an and running -6an nylon braided hose from there to wherever I need it.
I'm just concerned about the compression fitting coming off the hard line. The highest pressure one I could find was rated at only 50 psi

Rubber fuel injection hose works great. I flared the end of my hard steel lines with a 45* flare and installed 3/8" brass hose barbs. (If you have a 37* flaring tool, you can do the same with AN fittings.) I then pushed rubber fuel injection hose over the hose barbs. My personal experience with my setup is that once you push that rubber hose onto the hose barbs, the only way it's coming off is if you cut it off. Of course, you should still use fuel injection hose clamps, too. The brass 45* hose barbs and tube nuts were cheap - I got mine at the local Parker store, but Fastenal and Grainger have them, too. The type of fitting is called "SAE 45".
A lot of the pros use Swagelok fittings. Here is a commonly used compression fitting for adapting a 3/8 hardline to AN that is rated to more than 2000psi. It's also stainless steel and costs about $15. (SS-600-6-6AN). http://www.swagelok.com/search/find_...t=SS-600-6-6AN

If I had quick connects this would be easy. Lol
