Mechainiac, the photo helps. Looking at your, I have a threaded hole where you show the inlet line going. Then below, I have 2 threaded holes between your inlet line and the water drain cock, about 3" apart. Both follow along the ridge below the inlet line and one is almost straight below the inlet, the 2nd is 3" toward the rear. I would assume that either of those could work for the outlet line, but I'm curious as to what the second threaded hole is for. I wonder if one of the two was for the oil pressure gauge? You would think these would be pretty much the same on all 235's of that era. It obviously is set up for a by-pass filter. Thanks guys, and if anyone else has any input, let me know. If I can locate a digital camera, and if I can figure out how to post photos, I'll show you my setup.
