Fixed my check engine light
My Hummer H3 was throwing a check engine light due to a faulty gas cap, and this replacement cap solved the problem. It fits perfectly and seals tightly, preventing fuel vapors from escaping. The installation was a breeze, simply screwing it onto the fuel tank. It's made of durable ABS plastic and seems to be a good quality replacement for the original cap.

Just Like the Original
Because I have an almost 20 year old H3, it's not always easy to get replacement parts, especially wear and tear type items. So I ordered this gas cap when I saw it available. It's just like the original part and fits perfectly.
