Weaver 3 stage dry sump pump. Pump is off a Hutter 368 we ran at flemington. I have included all the Weaver parts I have, including, 4 new body sections and 3 overhaul kits. Also included is the Weaver pump overhaul book. If you can read you can overhaul one of these pumps. The scavange side of this pump was protected with filters. $500.00 obo Thanks.
