4-stage filter mount oil pump fresh from Barnes. This is the rotor style pump for improved scavenging. Bought a new one due to time constraints and had this one rebuilt later. Identical new one was $1800, will sell this one for $1000. Comes with new cam drive flange, pump, parts that were replaced by Barnes and receipt from rebuild. Not junk, I would run this on my motor with no worries. 317-646-8664. Indy pickup or buyer pays shipping.
