It's the Vacum Return port and is in EVERY Nova and Nova-based engine. Not a problem with stock engines, but modified engines, especially high HP ones, are seeing some issues. The video below explains everything.
I run all of Neal's Nova engine lines and have no issues with mine because I run Werks fuel, which is thicker than most.
