In essence no, but I tend to make mine a little more complex.
I angle the inlet (from the engine), so that the condensate is directed onto the inside of the 'pot', spiraling downwards. The steam outlet (to the funnel) I either have as a straight pipe that is flush with the inside edge of the top, or if I have a messy engine (heavy breather), then I may well bend the tube through 90 or even 180 degree inside the pot, so that it reduces the chances of condensate splashes finding their way out. The drain tube is a straight piece that goes right down to the bottom of the pot, and has a shallow slash cut end.
As ever, there are many ways of doing things, but this is how I make all mine, I hope it helps.
