Remi, I am not disputing whether or not one or the other location is best, it was only to state a fact of physics.
And then I wonder if a varying pressure in the return line can affect things like mixture control?
Air bubbles I would expect to be rare if not non existent, provided return flow is sufficient.

Alex,
In my opinion it depends on what fluid you are returning. You are right if 100 per cent liquid fuel is returned. Now if 100 percent vapor is returned, returning to the top of the fuel tank will significantly reduce the back pressure. Because one of the most important function of the return line is to allow vapor to escape the fuel system, therefore preventing potential vapor lock, I believe returning to the top of the tank is a better option.

Alex,
Varying pressure in the return line may affect the fuel pressure to the carbs, but as long as this fuel pressure stays within the limits specified by Rotax, it should not affect the mixture.
