I believe my fuel return line is leaking.

 I'm talking about the line on the rear of the cylinder head. I was under there fir something else yesterday and noticed it's wet on the back of the engine and down the bell housing. A small drip was handing on the bottom of the bell housing. It was fuel. Could see the light green color. 

 I took my phone and tried to get a pic behind the head (it's tight back there) and it looks wet. Can't tell if it's just the copper washers leaking or if it's the line itself. So far its a small leak, just a drip. 

 Could this cause a slight hard start issue? I noticed yesterday morning she seemed to start a bit harder than normal. (Temp was low/mid 40's)

 Thinking of just replacing the line, banjo and washers also whatever seals at the "T" as well.

 Any thoughts?

 See pics, best I could do in that small space.

Should I just do the seals or is it common for the line itself to go bad?

 

Typically the sealing washers go bad. I've had to replace a set on mine awhile back. No issues since. Typically the line itself doesn't go bad but the seals on the banjo bolt or the square cut o-rings at the return tee fail.

 Got the seals replaced today. Have to say it was much easier than I thought it would be. I removed the valve cover (and the one heater hose to allow pulling the valve cover off easier)

 So far no leaks apparent,  I used brake cleaner to spray off the top of the bell housing the best I could. I'll check it again after a few days.
