My canister looks like a shoebox and is located differently than yours, but the problem is the same. Unlike the 80 though, I've heard of very few people ending up with vapor lock while at the pump. I think our issue is different than the 80 in that way.
Our OEM cost is less than the Autozone one too. I bet if you did a new instal it would "fix" the issue until it happened again. (Sloshing fuel/pressure overwhelming the EVAP system)
OK, so I could not fill up all the way for a few months and dbl check the valves to make sure they are not sticking? Will the Charcoal canister then eventually not be saturated and thus not need to be replaced?
