Vent control system

A fuel vapor separator comprising:

• a fuel distribution network having a plurality of outlet ports configured to transfer fuel to one or more fuel injectors;
• an enclosed fuel chamber having a plurality of inlet ports configured to receive excess fuel from the one or more fuel injectors;
• a vent port configured to vent vapor from the excess fuel;
• and
• a closed biased vent valve disposed in the enclosed fuel chamber to regulate the venting of vapor from the excess fuel through the vent port, the closed biased vent valve including:
• a float having an upwardly extending float arm, the float arm having a downwardly facing hook;
• a lever arm having a single upwardly facing hook;
• and
• wherein the upwardly facing hook and the downwardly facing hook are coupled to one another when the enclosed fuel chamber has a fuel level below a predetermined level.

A vent control system comprising:

• an enclosed chamber having a vapor outlet;
• a closed biased vent valve that selectively opens and closes the vapor outlet;
• a float having an upwardly extending float arm movable vertically within the enclosed chamber to open the closed biased vent valve;
• and
• a lever arm connected to the closed biased vent valve, wherein the upwardly extending float arm and the lever arm contact one another when the float is located beneath a designated level in the enclosed chamber and constructed to completely separate from one another such that the lever arm has no contact with the float arm when the float rises above the designated level.
