Review on 🔒 Stant 10511Y Yellow Locking Cap for GM Flex-Fuel with Non-Threaded Filler Neck: Secure and Convenient! by Ron Coleman

This is the second option I bought for the 09 Impala 3.5L. I replaced the factory cap with one because I needed a lockout feature and the first lasted maybe 2 years before I started getting an EVAP system related check engine light. Replaced it and now it's sealed again and the EVAP code didn't come back. So I found that they don't last forever but are inexpensive. I bought a different brand locking cap for a 2010 Equinox and it is more difficult to lock and unlock but could be of better quality. The stand is very easy to use.
