With a return and an auxilliary electric fuel pump, you just run the electric pump for a minute or two before attempting to start a hot engine, and the vapor lock gets pumped back to the gas tank. I did not initially install a fuel return, but did so by Tee- ing into the fuel linehalf way between the two carbs and running a line back to the top of the fuel tank. I restricted it very simply by inserting a grooved plug of threaded stock into the line and clamping it with a hose clamp to the desired flow rate, about half a US gallon per hour seems to work fine. Rotax recommends a fuel return.
