all the drips should be burned by the exhaust blast as long as the valve is only open when the turbine is running and then closed before you shut down, otherwise you can hook an extra fuel solenoid up to the smoke line and Y it to the ECU fuel solenoid and it'll open only when the ECU has the fuel flowing to the turbine (turbine running). more convenient to some people, but more expensive to me so i just open the valve after i start up and close it before i shut down, I've got to where i do this on all my aircraft regardless if they are dribblers or not.
