This is an evap, right? Like, I know you aren't supposed to look after a certain amount of time. But, when I first took it, I thought I saw something faint buy wasn't sure so didn't count it as a positive. Well, about an hour later my SO see's the evap (I'm assuming) line. The first pic is within the time frame. And the second was an hour later. Can you see anything in the first picture?
