Evap lines? Edited, need more advice

Rayna
This is an Evap line, right? Right? How can one tell? 
The line was so so faint when I first did the test and I walked away from it because I had a phone call and was gone for maybe 20 minutes. I've heard Evap lines happen, but I don't really want to bother with another test. The DG where I am keep them behind the counter which is horrible to ask for 😩
I have another one down in the comments... I need opinions on that.
