To follow up on some of the recommendations that I received for my vacuum pump. The copper oil lines seemed to make a world of difference, they were solid, didn't leak, and seemed to keep the whole system cooler. I did turn up the flood dripper(the one i added on the intake) and that seemed to cut down on some of the smoke, as well as improved my vacuum. I did switch to Hi-tran hydraulic oil instead of the surge oil about 2 weeks into the season. 5 gallons for 65 bucks vs 70 and a 2 hour round trip for 2.5 gallons. I made sure to keep moisture out of the oil and had no foaming issues, maybe even less smoke? The oil i bought(2 different brands, one was amber, the other was blue just like the expensive oil) seemed to last in the system just as well if not longer. All the vanes and seals seemed to be no worse for ware. I also used a 110v box fan blowing over the pump and copper oil lines. I ran between 22 and 24" at the releaser around the clock for many days. I don't see any reason i can't get a few more seasons out of this setup, even though my brother really wants to spend a few thousand on a new pump.
