This cap fit perfectly on my vehicle and sealed tightly with no leaks. It’s a genuine GM replacement part, so the quality is excellent and it works just like the original. Easy to install and has held pressure with no issues since putting it on. A good, reliable replacement if your old one is worn out or cracked.

This fit the tank that was purchased for my T6500 GMC. I’ve now purchased a second to fit my other truck.
