2009 GT EVAP & Gas Tank capacity

[BC123]

Does anyone know if the EVAP system on the 2009 Vibe gas tank has a float to block fuel getting into the vent line?I'm asking because the tank is 13.0 gallons. The gas pump will usually auto shut off well before the tank is really full. I've found that if I am patient at the pump I can squeeze an a extra gallon or two of gas in the tank. This allows me to go over 300+ miles before needed to re-fuel. If I stop when the pump stops the low fuel light comes on around 250 miles. I have recently learned that overfilling the tank can cause damage to the EVAP system and soak the charcoal with fuel. This will cause the CEL to illuminate. I haven't had any problems yet (knock on wood) but hope someone here knows so I can either continue super filling the tank or stop before my luck runs out.Thanks GV!

Personally, after it clicks off the first time I add $3 or so. Usually that works out to somewhere around 2.5-3L or 3/4 of a gallon.... ish.Been doing this ever since I bought the car, now at 119000kms. No problems so far...If you smell fuel while driving just after you fill up or when you get home then IMO you filled it too much! Just my 2 cents!

So at almost $4/gal that would at most give me ONE more quart Not knowing the true capacity and where to draw the line, I feel this is playing it safe

...aren't all of the Vibe's tanks 13.2 USGallons (50 liters)?

Looks like I'm not the only one to try to feed the Vibe a little extra at meal time. Thanks for the feedback.

I almost always stop at the first click of the pump. Overfilling does terrible things to the evap system and that includes the charcoal canister. The canisters in newer cars like our Vibes are not vented to the atmosphere like the older cars, so once saturated with raw gas, it doesn't clear after a few miles, it stays saturated for a while. This, of course, causes problems in the evap system and never ending 'check engine' codes. Other problems are raw gas mucking up evap sensors and valves, requiring them to be replaced. And some are not cheap. The evap system in newer cars is designed to sacrifice itself to prevent fuel spills from over-filling, so the constant punishment for over-topping the gas tank could lead to expensive repairs.
