Mike, have you set your accusump on any angle?
Taken from "Accusump™" The sump will work with the tube in any position or orientation; however, if possible, mount the tube with the
oil end (the end with the
oil valve) slightly higher than the air end. This will prevent accumulation of air bubbles
(coming from foam in the
oil) by purging any minor air pocket during pre-oiling, when it will not cause any harm."
Might be of value +/- ?
