Abstract
A fuel delivery system has a tank, a fuel pump, and an air filtering apparatus coupled with the tank and the fuel pump. The air filtering apparatus includes a housing that defines a housing chamber, a fuel flow controller coupled with the housing, and a passive separator disposed within the housing chamber. The passive separator is constructed and arranged to separate air and fuel of a fuel mixture passively while the fuel mixture enters the housing chamber from the tank and while filtered fuel exits the housing chamber toward the fuel pump in response to operation of the fuel flow controller. Such a system is well-suited for supplying fuel to a combustion engine in which consistent fuel pressure may be critical. Furthermore, the passive separator alleviates the need for a power source for active air and fuel separation, a control mechanism, and so on.
