To avoid any confusion, refer to your vehicle’s manual for precise instructions.

Disconnect the fuel pump from the fuel injectors

Disconnect the pressure regulator

Refer to your car manual to determine if this step is necessary. If required, locate the pressure regulator and the vacuum line, and gently separate them to disconnect.
