I know that on a '96 the fuel filter is an in-line type near the fuel tank. As Pontiac hasn't really altered much on the Sunfire in over ten years, I'd suggest starting there.
The orifice tube on a 2002 Pontiac Sunfire is located in the air conditioning system, specifically within the liquid line. To access it, you typically need to follow the line from the condenser to the evaporator. The tube is usually situated near the firewall, where the liquid line connects to the evaporator core. Make sure to discharge the AC system before attempting to replace the orifice tube for safety.

I've never had to change mine, but it's an in-line filter located near the gas tank.
On a 2005 Pontiac Sunfire, the fuel filter is located along the fuel line, typically near the fuel tank. It is mounted on the chassis, just in front of the rear axle, and can be accessed from underneath the vehicle. For easier access, you may need to raise the car and secure it with jack stands.

Refrigerant is added to a 1997 Pontiac Sunfire by removing the safety cap on the low pressure cooling line at the rear of the engine compartment. The charging line is then hooked up and refrigerant added until the pressure reaches specified levels.
