Can anyone tell me if the best way to connect -6an ss braided line to this? I am doing an ls swap and run 6an braded line from the filter to this 3/8 line and am not sure how to connect to the flared hardline. I looked for a Russell fitting/adapter and couldn't find one. I'm a fuel system moron so any help would be appreciated.

 

If you cut off the flare you can use a compression fitting (also called a hard line fitting) .Check Summit or Jegs. I used one for my return line recently but don't recall the part number.
