ELECTRIC VACUUM PUMP RESULTS
#3
I bought two of them off of E-bay for 20 bucks apiece. You just have to watch for them, they are always on there for 50 or 60. Here is one for 60 right now. Item number 360182675334 on E-bay.
I'll try to post up some pics of the installation next week. And again this is with a 16v battery not sure of the results we would get with a 12v system.

Just make sure you don't get into a positive crankcase situation, or you may find out which seal is the weakest on the motor.
You might want to consider something like a roll over check valve in the valve cover. Something that will seal with vacuum, but vent with pressure. It'd be some cheap insurance to do that and not worry about pushing oil pan gaskets out and spraying the tires with oil.
Just food for thought.
