Fits great on my 2018 GMC Canyon
My 2018 GMC Canyon would leak diesel exhaust fluid. It would crystallize around the cap, and occasionally drip down the side of my truck. The factory cap seemed to be faulty, and I saw other comments online with people having the same problem. The dealer couldn't/wouldn't get a new one for me and didn't seem too concerned about the DEF leaking. It looked like this cap might fit so I tried it. Works wonderfully. No more leaks.

Decent aftermarket replacement
Plastic of the cap seems to be different than the factory cap. Will see how it holds up over time.
