Since you're using a D420, one more small point. We'll see if @lexvil concurs, but if you decide to use an angled connector, it needs to be a 110-120° version rather than 90°.
The width of the exhaust tee will restrict hose motion a little bit with a 90° connection. Like @lexvil , I'm coming from the left with my bailout bottle, but the principle is the same from the right with open circuit.
