Review on ACDelco GM Original Equipment GT329 Fuel Tank Filler Cap: Reliable and Stylish in Black by Luis Watts

I can't get over the gas cap. In general I am very satisfied with everything. Arrived on time and well packaged. The gas cap was actually a genuine replacement part (2010 Chevy Equinox 2.4L) and fitted in minutes (had to pull out the old line anchor which broke the old one). I bought this because my car was showing code P0449 "Evaporator Leak". "Large Leak Detected" even after replacing the faulty evaporator solenoid and making sure the gas cap was leaking. After some trial, error and browsing YouTube, I found out that a gas cap does a lot more than just cover the gas port ( haha sorry I'll continue). The cap not only needs to "snap" (i.e. click) but also hold pressure. Mine apparently wasn't. I never tested it but ordered a new OEM anyway as it was less than Costs $16.It says right on the cap that if you don't tighten the cap with a click the check engine light can come on.I replaced the old cap with this and gave it a click and.No more checking the engine light or fault code.If So if you get code P0449 you can replace it even if the gas cap is stuck I won't lie I think I'm pretty nimble under the hood but knew bi s recently that fuel caps can break, although they look perfect. A super cheap way to prevent cap leakage. Very happy with this purchase!
