P0449 Code

[drmiles]

When my canister gets clogged (Mudding) I get those same problems, but also I noticed that it is hard to fill the beast up form empty. The nozzle keeps clicking off. I guess because the vent is clogged. I can remove the hose blow it out, and usually beat it with a hammer to losen up anything inside. That usually fixes the problem. I always clear the code with a programmer. If it is not hard to put gas in from empty the vent is probably working.
