It is pretty simple, just remove the old ones ( in the centre of your axles sitting on top) Like a banjo union. Then replace with the new ones, making sure they are a good fit and water tight. Then the timing cover plate is 3 bolts on the front side of the timing cover on the other side to the FIP. You want to route the pipes out the way of moving parts like belts, suspension etc. Ideally ending up at the top of your snorkel!!!!
