No, I did the same thing after the last reassembly. Kinked one of the hoses and was building vacuum in the tank. Luckily I knew what it was the instant I cracked the cap.
I've been contemplating a complete redo of that whole system. Stay tuned for more information. I'll post details IF I ever get around to it. (Note: this will involve color coding, re-routing, and possibly SS braided hose. I'm tired of this crap. Poorly designed.)
