Abstract
A fuel vapor separator includes a polymeric body that preferably has a polymeric canister and a polymeric lid secured to the canister to define a liquid tight enclosure. The enclosure is preferably divided into at least two chambers. One chamber preferably receives liquid fuel and communicates with a heat exchanger to cool the supply of liquid fuel therein. Vapor is trapped in a vapor dome area above the liquid fuel and is vented through a vent valve carried by the fuel vapor separator. The other chamber of the enclosure preferably receives a high pressure fuel pump adapted to receive liquid fuel from the first chamber, and to deliver liquid fuel under pressure to the engine. Preferably, the chamber in which the fuel pump is received is communicated with a coolant to facilitate cooling the fuel pump in use.
