Need Car To Pass Smog

I have no experience with your vehicle but while it is true that your fuel pump is in your tank, the fuel filter is typically in the fuel line between the tank and the engine. Follow the fuel line out of the tank along the side of your car. You will run into a canister about 2 inches in diameter and 6 inches long that has a fitting on both ends (one in and one out). That is your fuel filter. Good luck.

I rather doubt the fuel filter is the problem. What exactly is the reason it fails inspection?

I see no listings for just the fuel filter for a 2006 Grand Prix. I checked all engine options. The YouTube video was probably showing an older model. A fuel filter is available for my 2000 model, for example. Don't waste your time or money replacing the fuel pump! Why won't the vehicle pass inspection? Check engine light on? Readiness monitors not set? If the check engine light is on have your local auto parts store scan the computer for trouble codes. Get the codes and post them here. We can help further. If your readiness monitors are not set simply drive normally for a few days with the gas gauge between three quarters and one quarter full. The readiness monitors will then set. Also remember that under Federal Law your vehicle will pass Emissions inspection with one readiness monitor not set. It doesn't matter what one is not set as long as all the other ones are set. Hope that helps! Jim
