I ordered a number of parts a few weeks ago in anticipation of the purge valve from the Airflow performance fuel injection system.
Today I installed it so that the return line runs to BEFORE the fuel valve and back to the right tank. This will allow a process by which I flush hot fuel to the right tank and fill the lines with cold fuel from the left tank ready for hot starts.
I don't know how it all works yet, however, I do know the lines are required and that the setup I have used is common.
