A fuel filter has a filter housing and a fuel filter insert exchangeably arranged in the filter housing and provided with a prefilter element and a main filter element. Prefilter element and main filter element are positioned one behind the other in the filter housing in axial direction of the filter housing. A fuel discharge channel is arranged in the filter housing below the fuel filter insert. In operating position of the fuel filter insert in the filter housing, the raw sides of prefilter element and of main filter element are sealed relative to the fuel discharge channel by seal-tight contact of the fuel filter insert on the filter housing. The raw side of the main filter element, when the fuel filter insert is moved by axial movement away from the operating position, is fluidically connected with the fuel discharge channel via the raw side of the prefilter element.

A filter system for filtering a fluid has a filter housing with filter housing head module and housing cover. The filter housing accommodates a filter element with raw side and clean side. A fluid inlet is in fluid connection with the raw side of the filter element. A fluid outlet is in fluid connection with the clean side of the filter element. The filter housing head module has a tube section as a main channel connecting the clean side of the filter element to the fluid outlet when the housing cover is attached to the filter housing head module. The tube section projects into the clean side of the filter element and has a ball valve seat of a ball valve for closing or opening the main channel. The filter housing head module has a pump chamber of a pump as a bypass channel bypassing the ball valve seat.

A priming pump may include a housing; an inlet passageway inside of the housing; an outlet passageway inside of the housing; a divider, inside of the housing, separating the inlet passageway and the outlet passageway; a connecting passageway through the divider in fluid communication with the inlet passageway and the outlet passageway; a valve, disposed in the connecting passageway, configured for one-way fluid flow from the inlet passageway to the outlet passageway; a rotary pump, inside of the housing, having an inlet in fluid communication with the inlet passageway and an outlet in fluid communication with the outlet passageway; and a shaft connected to the rotary pump and extending through the housing, the shaft configured for rotation by an external driving mechanism.

A fuel system, including a first pump, a second pump and a filter module. The filter module has a housing defining an interior, a filter received in the interior, a filter inlet through which fluid flows into the interior, a filter outlet from which fluid flows out of the interior, and a vent body received within the interior. The vent body has a passage and a vent orifice. The filter is arranged so that fluid that enters the filter inlet flows through the filter before flowing out of the filter outlet and the interior includes an upper portion arranged above a lower portion relative to the force of gravity, and the passage communicates with the filter outlet and with the lower portion of the interior and the vent orifice communicates with the passage and with the upper portion of the interior.

A fuel pump module for a vehicle, which is formed in a low-floor type fuel pump module capable of being easily installed in a fuel tank with a reduced vertical height. The fuel pump module includes a head plate to be mounted in an opening of a fuel tank, a reservoir cup to which the head plate is pivotably coupled through a pair of connecting bars and which is to be installed in the fuel tank in a state of being coupled to the head plate, a fuel pump disposed in the reservoir cup in a state of being laid and to deliver fuel in the reservoir cup to an outside of the fuel tank, and a jet pump installed in the reservoir cup and to suction fuel outside the reservoir cup and discharge the fuel into the reservoir cup.

The present disclosure relates to a fuel pump module, and more particularly, to a fuel pump module including a flange module and a reservoir module, in which when a fuel delivery pipe for supplying filtered fuel from the reservoir module to the flange module is coupled to the reservoir module, since the fuel deliver pipe may be coupled to the reservoir module to a desired position in an axial direction and to be prevented from rotating in an axial direction, the fuel delivery pipe may be prevented from interfering with a guide rod connecting the flange module and the reservoir module in a vertical direction, thereby not only preventing the occurrence of fire, but also increasing a common use rate of the reservoir module.

A portable pump and fuel containment system includes a portable base assembly including a lower support and wheels, a container on the lower support including an interior volume and inlet and outlet ports in fluid communication with the interior volume, and a liquid transfer assembly coupled to the portable base assembly. The liquid transfer assembly includes a pump, a three-way control valve, a flexible transfer line having a first transfer line segment coupled to a first inlet of the three-way control valve and a second transfer line segment extending from the outlet port to a second inlet of the three-way control valve, and a flexible return line having a first end coupled to the outlet of the pump and a second end detachably coupled to the inlet port of the container. An outlet of the three-way control valve is connected to an inlet of the pump.
