Gordon, I really like what you did there. But multiple 90s aren't great for flow unless they are sweeps...
AN-8 180s are like $20 each, but are a smoother way to reverse direction. As my buddy Stan says, buy/cry once.
That may all be true, but its been working and cooling fine for 16 years now without a hiccup. I never needed any 180º connections - the worse is an occasional 90º but on the latest hose routing version I used more 45º fittings due to better routing (all things get better after you think about it more).
So I guess you can mount the filter any way you wish and then just work up a method of spinning it off and catching the drain oil. Whatever fills your drain pan!
