Review on GM Genuine Parts 215-608 Vapor Canister: Superior Quality and Performance by Mario Bullard

I had a tank vent problem on my GMC Sierra 04 where no fuel would be drawn in unless the injector was perfectly positioned and on the right one speed vented. After the purge valve reservoir didn't fix the problem, I'm pretty sure that was the problem. Of course now I can pump just as fast as everyone else at the gas station lol. A bit difficult to replace with the OE canister still in place, after so many years things tend to be stubborn. I think I ended up needing a 5/8 heater hose and some clamps (it's been a few months since installation) but overall it was worth the time.
