A fuel module for pumping and filtration of a fuel in a fuel system includes a flow housing, and each of an electrically powered pump, a first cartridge filter, and a second cartridge filter in sealed, direct engagement with the flow housing. The fuel module is applied in a low pressure fuel circuit feeding fuel to a high pressure fuel circuit for pressurization to an injection pressure. Electronic closed loop control techniques for the pump are also disclosed.

A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system.

A fuel filter device includes a filter cloth and a skeletal structural member including an inner flange portion positioned inside the filter cloth and a connecting member including an outer flange portion positioned outside the filter cloth, wherein a peripheral edge portion of an opening of the filter cloth is clamped between the inner flange portion and the outer flange portion, the inner flange portion and the outer flange portion jointly defining a center hole and a center bore serving as a communication passage communicating inside of the filter cloth with outside of the filter cloth, and the inner flange portion is provided with a sealing rib to compress the filter cloth to ensure a sealing performance thereof, a welding rib to join the skeletal structural member and the connecting member with each other by welding, and a shifting preventing rib configured to restrict shifting of the filter cloth.

Techniques for managing a fuel for a power generator include storing a volume of a fuel in a primary fuel storage tank that includes an inlet and an outlet; generating electrical power with a solar power assembly; operating a pump assembly with the generated electrical power to circulate a flow of the fuel from the primary fuel storage tank to a fuel filter; removing at least a portion of contaminants from the flow of the fuel; circulating the flow of the fuel to a fuel quality sensor; measuring a quality value of the flow of the fuel; and based on a signal from the fuel quality sensor associated with the quality value of the flow of the fuel, operating a control valve to direct the flow of the fuel from the fuel quality sensor to the primary fuel storage tank from the control valve or an auxiliary fuel storage tank from the control valve.

In at least some implementations, a jet pump includes a main body having a first inlet, an inlet passage communicated with the inlet, a second inlet, an intake passage communicated with the second inlet, an outlet, and an outlet passage communicated with the outlet and with the intake passage, a jet carried by the main body and having a jet inlet communicated with the inlet passage so that fluid flowing in the inlet passage flows through the jet inlet, and a jet outlet having a flow area less than the jet inlet and less than the inlet passage. The main body is formed in one piece and the jet is a separate piece of material that is inserted into the inlet passage after the main body has been formed.
