Review on 🚗 Dorman 577-379 Fuel Filler Neck for Compatible Vehicle Models by Sam Duppa

Product fits the car like a glove EXCEPT at the end of the filler neck where the cap attaches DOES NOT ACCEPT the factory gas cap. I saw another post after the check engine light came on and now I can't pass the exam. The gas cap appears to be locked, but you can remove it immediately. This is a 2003 Chevrolet Trailblazer. Called Dorman a week ago and as of this writing they still haven't found a solution. It's easy - just send me the part you need! This is a good company and their products are usually great, but this is a fail. I will post an update when possible.
