So this is my first "real" plumbing job. It's a high pressure fuel system for EFI. I have 3/8" stainless hard line running the length of the frame rail. I think I've got everything figured out, except, I'd rather not use hose and clamps (The good efi type high pressure clamps, not a worm clamp), so what's the accepted method of plumbing hard 3/8" stainless line to -6 AN braided hose? I see tube to AN adaptors but they say they are for aluminum tube? I have stainless tube, and the pressures involved here are at least 55psi. Do I flare the tube 37degrees (AN style) and find a fitting for that? I must be missing something stupid here, because I'm sure people use hard line and are not running hose for the whole fuel system.
