Hole for Fastener too short as stated by others
This does fit the Purge valve opening but is not long enough to fasten. Had to open up with cutting wheel to make it work

Works
I needed this to plug the LS MAP port because I am using the Terminator built in MAP on my car. Lube the O ring, and no problem.
