Leaking fuel return line

[Mobile Mac]

Hi guys I am new to this forum. Im Mobile Mac..I have a couple problems with my baby(my explorer)...I recently changed the fuel pressure regulator and the return line that snaps on the top seems to leak from time to time. Gas is too expensive for that..I replaced the o ring with a new one and it still seems to leak. I even put some motor oil on it...It is not the screw on type. Can anyone give me any tips PLEASE!!

Welcome to the forum. Wish I had a good answer for you, but I haven't a clue why it would still be leaking. I would check for any nicks, or perhaps a small crack in the line.
