Procedure:

Safety First: Ensure your safety by wearing appropriate safety gear such as gloves and safety glasses. Also, work in a well-ventilated area.
Depressurize the Fuel System: To release the pressure in the fuel system, remove the fuel pump fuse or relay. Allow the engine to run until it stalls. This depressurizes the fuel lines.
Raise the Vehicle: Safely lift the front of the vehicle using a jack and secure it on jack stands.
Locate the Air Pump: The air pump in a 2008 Mazda RX-8 is usually located near the front of the engine bay.
Disconnect Hoses and Wiring: Carefully disconnect any hoses, wires, or connectors attached to the air pump.
Remove the Air Pump: Use the appropriate wrenches or sockets to remove the mounting bolts or screws that secure the air pump in place. Carefully take out the old air pump.
Install the New Air Pump: Position the new air pump and secure it with the appropriate mounting bolts or screws. Make sure it's properly seated.
Reconnect Hoses and Wiring: Reconnect any hoses, wires, or connectors that were disconnected earlier.
Torque to Specification: Tighten the mounting bolts or screws to the manufacturer's torque specifications.
Lower the Vehicle: Carefully lower the vehicle from the jack stands.
Check for Leaks: Once the vehicle is lowered and the engine is started, inspect the air pump and connections for any signs of leaks.
Please note that this is a general guideline, and the specific process for replacing the air pump may vary depending on your 2008 Mazda RX-8 model. Always consult the manufacturer's service manual for precise instructions and safety precautions.
