The oil sending unit just screws out. Remove the wiring to it first, and then using a ratchet, unscrew it. NOTE: Because of the odd head on it, a special socket is needed. When you purchase the switch, look at it to confirm you have a tool that will work. If you don't, the parts store will most likely have the socket you need.
Let me know if you have other questions.
