Abstract: A fuel additive system of a fuel delivery system of a vehicle includes an additive tank assembly, and a dosing unit in communication with the additive tank assembly to control the amount of additive dosed to the fuel tank. The additive tank assembly includes a pressurized tank of generally torispherical or ellipsoidal shape, a tank conduit with one end in communication with a sump in the pressurized tank and an opposite end extending out of the pressurized tank, and a valve in communication with the tank conduit near the opposite end thereof and being normally closed under pressure from the pressurized tank. The dosing unit includes a housing having an inlet passage in communication with the tank conduit, and a valve actuator in the inlet passage to displace the valve of the additive tank assembly to an open position once the dosing unit is assembled to the additive tank assembly.

Abstract: A gas and liquid separation device for use with a fuel tank. The separation device includes a body having at least one passage therethrough in fluid communication with the fuel tank, and a gas and liquid separator carried by the body in fluid communication with the at least one passage and being oriented at an angle with respect to horizontal when in use.

Abstract: A fuel pump module adapted for mounting within a fuel tank and including an inlet, an outlet downstream of the inlet, and a fuel pump downstream of the inlet and upstream of the outlet. A fuel filter chamber is downstream of the fuel pump and includes a fuel filter disposed therein having an upstream side and a downstream side. A filter drain conduit is in fluid communication with the fuel filter chamber at the upstream side of the fuel filter and extends externally of the fuel pump module and fuel tank. The filter drain conduit may be in fluid communication with the filter chamber substantially at a lower portion of the fuel filter, and may include a valve located externally of the fuel tank. A heating device may be provided in the fuel filter and a recirculation device may be provided in the drain conduit.
