Does anyone know why on a 235 full oil pressure conversion,the diagram on the tech tips section, does not use the original hole from the engine to the filter. It would be the hole with the oil pump under it in step 2. Also in step 2 if you do not use the old hole do you have to angle the new hole to the left to intersect it. If not is that just an open rail that runs dow the side of the engine?
