Would anyone happen to know the part number for a "Fuel Tank Pressure Sensor" for a 2003 Pontiac Sunfire? Also can anyone tell me where on the car it's located and how difficult it would be for a novice to replace it? Forgive me if this information was posted before, but I found no results when I searched. Any help is appreciated as I am trying to help someone in need. Thanks

The fuel tank pressure sensor is located on top of the fuel sender. You need to drop the fuel tank and the sensor just pulls up.

Exactly what I needed to know. Thank you!

You can get the part from autozone. You don't have to drop the tank, cut a hole under the back seat. Over the hump, slightly to the right. Or just drop the tank.
