The Moroso dry-sump and external oil pump primer is a tool intended to prime pumps used in dry-sump or external oiling systems before initial engine start. It helps move oil into the pump and feed lines so lubrication is established prior to running. Practical for racing and custom oiling setups, the primer aids safe first starts by ensuring oil delivery in systems that do not rely on a conventional internal pump pickup.
