First, identify whether you should be replacing the oil pump. If it's just low oil pressure you probably have worn bearings. If you insist on doing just the oil pump: First, drop the pan. You will need to raise or remove the engine to remove the oil pan. Once the pan is down you should see the oil pump pickup syphon hanging down. Drop the oil pump by removing the bolts, then it should just drop in your hands.
