Methods and systems are provided for determining a source of degradation stemming from a vehicle fuel system during a refueling event. Specifically, in one example a method may include responsive to a refueling lock that enables access to a fuel tank of a fuel system being manually unlocked in order to add fuel to the fuel tank, monitoring a pressure in the fuel system and a fuel level in the fuel tank during refueling the fuel tank, and indicating degradation of the fuel system as a function of both the pressure and the fuel level. In this way, fuel system degradation may be pinpointed during a refueling event that is enabled via manual unlocking of the refueling lock.

Exemplary sanitary soap refilling systems and methods are disclosed herein. An exemplary refill refilling system includes a housing, a pump located within the housing, and a bulk storage tank connector. The bulk storage tank connector having a liquid outlet and an air inlet. A liquid inlet conduit is in fluid communication with the pump the liquid outlet. A refill connector is included. The refill connector has a liquid inlet and an air outlet. The refill connector air outlet and the bulk storage tank connector air inlet are in fluid communication with one another. The refill liquid inlet is in fluid communication with the pump.

A method for detecting defective gas flow in a vent line of a device for purging a fuel vapor absorption filter of a vehicle's internal combustion engine during filling the vehicle's tank with fuel from a filler nozzle having a venturi effect duct, so as to stop the filling when the duct is full of fuel. The vent line connecting the fuel tank to the filter. The tank having: a filler pipe, at the end of which is a stopper designed so that, during filling with fuel from the filling nozzle, fuel vapors are evacuated through the vent line. At least one gauge measures fuel volume in the tank. The detection method continuously measuring the volume of fuel in the tank during filling and comparing a volume profile thus measured with respect to time against a predetermined volume profile. A defective flow detected if the two profiles do not match.

The invention relates to removal equipment for removing fuel from a fuel container for fuel cells, wherein the removal equipment comprises: a sealing element for sealing an opening in the fuel container; a fuel line for establishing a first fluid connection between a fuel removal opening in the sealing element and a liquid fuel inside the fuel container; a float suitable for floating on the liquid fuel within the fuel container; and a flexible pressure equalisation line for establishing a second fluid connection between a gas region inside the fuel container, more particularly above the liquid fuel, and a pressure equalisation opening in the sealing element; wherein an end section of the pressure equalisation line is connected to the float. The removal device according to the invention is characterised in that the float is equipped with a damping device for damping impacts of the float against a wall of the fuel container.

Disclosed is a device for filling tanks from a canister with a first adapter device which is suitable for at least intermittent fastening to the canister and which has a delivery device by which a flowable medium can be conveyed out of the canister into the tank, wherein the device has a flushing agent connection in order to deliver a cleaning liquid to at least one component of the device. The device has a further receiving container to temporarily receive the flowable medium to be introduced into the tank, and the device has a measuring device which is suitable and intended to determine the amount of liquid to be introduced into the tank.
