I sent my RSA-5 fuel servo and flow divider to Airflow Performance for evaluation/overhaul. I have a Lycoming IO360-A1A. My question comes when re-installing the servo on the sump. I have new gaskets coming but would like to know the right way to prepare the mating surfaces and also whether I need to apply any goop to the gaskets when installing. If so, what kind of goop should I use.
Thanks as Always!
