Abstract
A method of manufacturing and assembling a carbon canister for a fuel vapor management system of a vehicle includes injection molding a housing partially defining a first chamber, a second chamber, a third chamber, and a baffle. The housing includes a first wall defining an interface between the first and second chambers and a second wall with a portion of the second wall defining an interface between the second chamber and the baffle with apertures proximate a first side of the housing. The method may include injection molding first and second retention plates, filling first, second, and third chambers with carbon pellets, installing the first retention plate into the second side of the housing proximate the first and second chambers to enclose the carbon pellets, and installing the second retention plate into the second side proximate the third chamber to enclose the carbon pellets in the third chamber.
