ABSTRACT:
A fuel reservoir system for an internal combustion engine includes a canister (22) having a storage volume (24) for holding fuel, at least one fuel supply line (26) extending from the canister to the engine, an entrance pipe (28) for conducting raw fuel into the canister, and an exit pipe (32) connected with a fuel supply line for conducting fuel from the canister to the fuel supply line. The exit pipe includes a draft tube (34) extending into the lower part of the storage volume, a purge passage (36) communicating the upper portion of the draft tube with the storage volume, and a flow restrictor (38,40) mounted in the draft tube upstream of the purge passage.
