Black water stink

[jeanathon]

I'm about to replace some hoses to get rid of the stink, but I am wondering if the flexible tank is also permeated. Do these tanks need to be switched out also?

Top quality flexible tanks rarely if ever permeate but cheap ones can. Without knowing the quality of yours. Fwiw, even the best ones have only about a 15 yr lifespan, so depending on the age of yours, and whether it's been subject to any chafing, it may be time to replace it.
