Abstract:
A fuel line coupling system for coupling a fluid fuel transportation tanker to a fuel supply tank and subsequently to a fuel destination depot tank, the system comprising a supply tank fuel transfer coupling component; a tanker fuel transfer coupling component to couple with the supply tank's coupling component for transfer of fuel to the tanker; and a depot fuel transfer coupling component to couple to the tanker fuel transfer coupling component for delivery of fuel from the tanker to the destination depot tank, wherein the tanker coupling component has an adjustable setting fuel type designator means and each of the supply coupling components and depot coupling component have a respective fuel type identifier means each of which identifier means is adapted to operatively interact with the fuel type designator means to physically prevent coupling when the destination depot tank coupling component fuel type identifier means and the supply tank coupling component fuel type identifier means are incompatible; the fuel type identifier means each being provided at or near the coupling end of the respective coupling component and comprising an identifying physical feature that co-operatively engages with a complementary physical feature on the fuel type designator means and the fuel type designator means being provided at or near the coupling end of the tanker coupling component and in such a way as to be adjustable while mounted to the tanker coupling component to alter the complementary physical feature that is presented for co-operative engagement, to thereby enable the designator means to be set for a required fuel type and only allow coupling together of the tanker coupling component with a supply tank or depot fuel transfer coupling component when the fuel type designator means and fuel type identifier means are compatible and co-operatively engage with each other;wherein the designator means comprises an annular plate that is rotatably mounted to the tanker fuel transfer coupling component, whereby rotation of the annular plate adjusts the setting of the fuel type designator means.
