Review on ACDelco GT139L Original Equipment Locking by Christian Poojary

I wanted to wait 9 months to see if it works before writing a review. I sprayed it with Boeshield T-9 anti-humidity spray when first installed. It still runs perfectly and smoothly with weekly gas fills. I drilled a hole on the side of the thumb grip 1/4" from the lock barrel and used thick fishing line to make a "cap tie" so it would be easier to find after filling. I wish the manufacturer had a pre-drilled hole provided so that the cap can easily be lost at the gas station.
