VEHICLE FUEL SYSTEM

摘要

A fuel pickup may include a fuel pickup tube having a plurality of holes for receiving fuel from inside a fuel container. A wicking material may envelop at least one of the plurality of holes. Aircraft fuel systems including such a fuel pickup are also disclosed. A vent-on-demand fuel sump and vehicle fuel system having such a fuel sump are provided. The fuel sump may include a pressurized vessel and at least two sensors configured to detect a level of fuel within the vessel. A valve coupled to the vessel may be configured to release air and/or fuel vapor to the atmosphere. The fuel sump may also include a programmable electronic controller configured to modulate the valve between a closed position and an open position based on signals received from the sensors corresponding to the fuel level.
