Yeah, so I've had the code for the evap canister up for probably a year and a half now and just been too lazy/cheap to fix it, but now I'm thinkin of selling the truck and would like to prevent that code from popping up anymore. Now, I know what causes it is the hose I ripped off of the canister attaching a tow rope off-roading, but I don't know which one. Well, at least where it goes... it's the lower of the two smaller ones. The truck is a '98 4 door Blazer, so the hoses are facing the back of the truck, and if you look at it from the hose end, it has two small hoses towards the top and one big on at the bottom. Which hose is the smaller one that sits on the bottom so that can go order the replacement parts? I started to trace it back, and it appears to be the one going to the engine compartment, but there's that lazy thing again... I lost it and figured I'd try here again. Any help?
