I was more getting at... how did you color them? where did you get them? what are they made of? how much were they? Did you have a reason/failure that lead you to change them or change their color?
PS: Dave I haven't forgotten you, I hope to be PM-ing you anyday
I actually worry that the oil from the filter, when its changed, is going to degrade the rubber hoses over time and be an issue in 5-10 years.
