The connection you are looking for should be a 90 or 45 degree -4 fitting slightly down and to the right form the temp sensor location when viewed from the rear of the engine. Its probably only 3 or 4 inches away from the temp probe. It is not part of the oil filter adapter assy but screwed into the accessory housing itself. I would think that all models of 320 / 360 would have this fitting or at least have the hole plugged. You should not use the oil cooler line for pressure measuring though because its only in use when the temp rises above 180 degrees F. Good luck ! Lloyd
