Most of the decent engines I have come across ran a Star Machine Vacuum pump.




I decided on a Star for one major reason they do not pull anything directly into the pump. Everything goes thru their VACUUM PUMP OIL SEPARATOR/EXHAUST TANK
first thus no trash that can tear up the rotors. All other designs require oil be passed into them. Star pumps are designed to run dry.

The Pump is a “OIL-LESS” design, which requires NO LUBRICATION for operation. Oil in the Pump will not damage the Pump,
however it will reduce its performance. The dryer you can keep this Pump, the better it will work!

VACUUM PUMP OIL SEPARATOR/EXHAUST TANK This new vacuum pump accessory is yet another example of Star Machines’ continuing effort to offer only the
finest vacuum components to the motorsports industry. Constructed of aluminum and CNC machined, the tank
can be completely disassembled if necessary. The “tank within a tank” design incorporates two separate
chambers. The inner oil separator chamber, containing a baffle and filter media, acts to reduce or eliminate oil
reaching the vacuum pump. A secondary benefit of this section is its ability to trap debris resulting from engine
failure before it can reach the vacuum pump and cause damage. The outer chamber serves as a free flowing
exhaust vent for the pump and also contains filter media. Separate drain cocks located in the bottom plate will
individually drain both chambers.
