Yes, it used to work that way here. I don't believe it's USA only though, this environmental protection system appears to be used in Canada as well. Apparently these systems aren't needed any longer as vehicles built since 2006 have vapor recovery systems built in (which is also why it's detrimental to your vehicle to "top up" your fuel tank now).
- db65edfc7996 5y ago>(which is also why it's detrimental to your vehicle to "top up" your fuel tank now) Could you expand on this a bit?
- rainbowzootsuit 5y agoI'm not sure if this is an interaction with the vapor recovery on the fuel pump nozzle, but topping up on some vehicles will introduce liquid fuel to the fuel vapor charcoal canister in the emissions system of the vehicle. It's not able to readily purge the liquid fuel and can case emissions codes and replacement of the fuel vapor canister can be needed to remedy.
- bonestamp2 5y agoYes, as the other comment explained... because fuel vapor recovery is now built in to newer vehicles, you should no longer "top up" your tank. Some people add a little more fuel after the pump stops the first time -- this is referred to as "topping up" your tank. That extra fuel goes into the charcoal canister and may require premature maintenance costs/time.
