A vapor storage canister incorporates a liquid trap that protects the carbon bed, but which avoids purging liquid directly out of the trap. The trap consists of a cup that forms an interior cavity at the bottom of, and surrounded by, the carbon bed. The purge tube does not enter the trap directly, but instead runs to a plenum that draws from the bottom face of the carbon bed. The trap, in turn, is open to the interior of the carbon bed only through a screen mesh grid. Consequently, vapor can be pulled from the trap at purge, but not liquid.

A fuel vapor storage canister uses a single canister body and a series of three possible modular liquid fuel trap subassemblies that fit into a trap housing of the canister body so as to allow the assembly to be installed in three differing orientations.
