Forceps come in handy when connecting the fuel lines to the primer bulb after reassembly of the case. You will need to remove the screws from the rear handle to access a couple screws in that area, be careful about the trigger and the trigger lock parts coming out. disconnect the front handle from above the chain cover, and remove the screw holding the rear handle spring and take the screws out from around the outer edge of the left case half, and remove the oil cap and the case half should slide off. Just be careful when reassembling because the fuel lines going into the tank can get pinched if not aligned with the holes in the two case halves when reassembling.
