Abstract
An on board refueling vapor recovery system includes a first fuel vapor passage for connecting a fuel tank with a canister, a second fuel vapor passage for connecting an inlet portion of a fuel filler pipe with the fuel vapor passage (a tank main body) and a check valve in the second fuel vapor passage. The check valve is integrated with a first quick connector of a resin hose (a resin tube) which constitutes the second fuel vapor passage. Therefore, the number of man hours required for assembling the on board refueling vapor recovery system can be reduced. In addition, the space required for installing any of the on board refueling vapor recovery system can also be reduced. Furthermore, the amount of released fuel evaporative emissions or fuel evaporative emissions can be reduced.
