I'm by no means an expert but I think a faint line is just a line that isn't very dark in color but that shows up within the window of time the test says it will (the ones I've used have been around 10 minutes). An evap line, I believe, shows up after the test time window. So, if the instructions say to wait 10 minutes and you don't get a positive, throw the test out and don't look at it again. If you come back to it an hour later or so you're likely to see a blue line - and that is the evap line and not a positive result. Like I said, I'm no expert, but that is what I've read. Good luck for a real blue line!
