Rob,
If you are looking to filter the scavenged oil before it returns to your oil tank, I would not use an Oberg filter. This is exactly the best place to put a good filter but the Oberg screen filter is not the one to use. I would highly recommend the Pall 7500 spin on filter assembly with a Pall 6 micron filter. You can actually get most of the parts on E Bay and when you are done you will have a return filtration system that is multiple times more efficient than the Oberg and really protects your engine. Pall is the world leader in filtration and their filtration media is the most efficient, far better than the Oberg "chicken wire" elements. Talk to Buddy Walker, the flat head Cad man, about his system, he uses the Pall 7500 spin on and is very happy with it. Filtration systems are like crash helmets, if you have a $5 head then buy a cheap helmet, same for your motor. You have put literally thousands of $ into it why protect it with a filtration system that is based upon 1940 technology!
