Perfect fit, fast delivery , check engine light went out. What more could I ask for. And the wife is happy about that.

I received this part on time - no -problems. The ONLY thing that could have made it better would be some directions on how to swap it out - especially with the connection to the gas cover itself.

Tried various aftermarket gas caps on my 2001 Buick Park Avenue to get rid of the check engine light. This is the only cap that worked.

Cap fits just like original. The How to video is a great help. It took care of the check engine light that has been on for several months. 1A Auto is my go to company.
Perfect fit!

Which model and year of automobile are you talking about. Would love to help you but I do not know your situation. I would recommend you call a dealer parts dept and make sure of your requirements. Different cap requirements for fuel injected and carburetor cars.
