Review on ACDelco Professional 12F51 Fuel 🔒 Tank Cap: Secure and Stylish in Black by Michael Rosario

Well, it's hard to get excited about the gas cap, but. My car's check engine light came on randomly. I scanned the trouble codes and they said "P0440 - Small leak in evaporative emission system". An internet search suggested checking the gas cap for a missing or worn o-ring or rubber seal. I found mine (probably an original over 10 years old) had dried out and cracked. Long story short, even though I have a KIA, the Delco AC cover fitted perfectly and solved the problem as the check engine light hasn't come on since. I paid just over $7 with shipping, which was cheaper than the popular Stant brand in stores and a lot cheaper than a real KIA.
