Actually, you haven't hijacked any of my threads. I've just noticed you trying to hijack a few others. Hijacking a thread means changing the subject, or trying to change the subject of someone else's thread to suit your needs. You usually don't succeed as most just seem to igore you.
You also ask questions that there are already answers to. The very same thread that you yourself linked to about the dyeing of hoses, has all the info you need. It tells you what kind of dye, it tells you exactly how to do it, how much water, how much dye, etc... Yet you still asked these questions.
I'm not trying to be a jerk here. I'm just pointing out that this may be why nobody answers your posts. The info is there. Read.
