Clutch Hydraulic Fluid Leak Question

[dank]

I noticed a slight leak on the left side in the area of the kickstand. Pulled the cover and it is hydraulic fluid from the clutch line. The source appears to be at the fixture where the line connects to the mechanism. (That was the highest elevation wet area and had a couple visible drops hanging on it.) I cleaned everything up. I tightened that connector's bolt about 1/8 to 1/4 turn, which was all I could tighten it. Everything else was too snug to tighten at all. Warmed the bike up and pulled the clutch lever 200 times. No drip anywhere.

My question for the better mechanics: Is there any reason to think the system encounters higher pressure and will leak under riding consitions? I don't see why it would, but I often find BD and others know things about how these systems function that are way beyond my knowledge.
