3911 fb black tank flush

[Squarebarrel]

I am trying to flush both black tanks on my 3911FB but only have 1 hose hook up. Does this flush both tanks?

Correct.

We have a 3911FB as well and noticed that the black tank flush appeared to only flush the second tank. That was confirmed by our dealer. Seems odd that they would provide a flush for one tank and not the other.

My money is on the chance the dealer doesn't know stink about what he's talking about.
