Place the fuel sending unit cam onto the tank and turn it clockwise a quarter turn with the specialized tool.
Use the straps, bolts, socket and ratchet to jack the tank back up under the Camaro and secure it.
Use the socket and ratchet to reconnect the negative battery cable to the negative battery terminal.
I hope the above helps.
