Looks evap lines to me xx Red dye for sure. Good luck xx
I agree they look like evap lines. I did this exact test with my LO and it came up with a blue cross straight away. I would do another one to make sure but a different test xx
I also think these look like evaps unfortunately x
They look like evap line, but these tests aren't really reliable to confirm my thoughts. For sure try the red dye as you said 😊😊
