Abstract
Abstract A reserve fuel tank is connected between the fuel filling inlet and the main fuel tank. Fuel enters the main fuel tank via a bypass conduit extending from upper side of reserve fuel tank to the main tank inlet by overflow after filling of the reserve fuel tank. A controllable valve is located in the main tank inlet between the bottom of the reserve fuel tank and the top of the main fuel tank for the release of fuel stored in the reserve fuel tank, when needed.

Claim 1
Independent Claim
243 words
A reserve fuel system for an automotive vehicle having a fuel filling inlet extending from outside the vehicle, a main fuel tank and a main tank inlet for directing fuel into the main fuel tank for operating the vehicle, said reserve fuel system comprising a reserve fuel tank positioned above the main fuel tank and connected between the fuel filling inlet and the main tank inlet whereby fuel passing through the fuel filling inlet passes through the reserve fuel tank, filling said reserve fuel tank before fuel flows into the main fuel tank; valve means in the main tank inlet between the bottom of the reserve fuel tank and the top of the main fuel tank; bypass means extending from the upper side of the reserve fuel tank above a reserve fuel level to the main tank inlet whereby when the valve means is closed fuel flows into the main fuel tank via the bypass means after the reserve fuel tank has been filled to overflowing with fuel; and valve control means for controlling the operation of the valve means, the valve control means comprising electromagnetic means controllable by an operator of the vehicle to an open position in which fuel in the reserve fuel tank flows directly into the main fuel tank via the main tank inlet and a closed position in which fuel flows into the main fuel tank only via overflow in the reserve fuel tank via the bypass means.

A reserve fuel system for an automotive vehicle having a fuel filling inlet extending from outside the vehicle, a main fuel tank and a main tank inlet for directing fuel into the main fuel tank for operating the vehicle, said reserve fuel system comprising a reserve fuel tank positioned above the main fuel tank and connected between the fuel filling inlet and the main tank inlet whereby fuel passing through the fuel filling inlet passes through the reserve fuel tank, filling said reserve fuel tank before fuel flows into the main fuel tank; valve means in the main tank inlet between the bottom of the reserve fuel tank and the top of the main fuel tank; bypass means extending from the upper side of the reserve fuel tank above a reserve fuel level to the main tank inlet whereby when the valve means is closed fuel flows into the main fuel tank via the bypass means after the reserve fuel tank has been filled to overflowing with fuel; and valve control means for controlling the operation of the valve means, the valve control means comprising electromagnetic means controllable by an operator of the vehicle to an open position in which fuel in the reserve fuel tank flows directly into the main fuel tank via the main tank inlet and a closed position in which fuel flows into the main fuel tank only via overflow in the reserve fuel tank via the bypass means.
Claim 3
Dependent Claim
64 words
A reserve fuel system as claimed in claim 1, wherein the bypass means comprises a bypass conduit extending from the upper side of the reserve fuel tank above the fuel level to the main tank inlet allowing overflowing fuel in the reserve fuel tank to flow into the main fuel tank bypassing the valve control means holding reserve fuel in the reserve fuel tank.
