A fuel level indicator indicating a fuel level in a vehicle fuel tank and disposed proximate a cap for closing a refueling orifice extending from the fuel tank. The fuel indicator indicates the fuel level in response to a fuel level sender unit disposed in the fuel tank. According to one embodiment
A fuel level indicator indicating a fuel level in a vehicle fuel tank and disposed proximate a cap for closing a refueling orifice extending from the fuel tank. The fuel indicator indicates the fuel level in response to a fuel level sender unit disposed in the fuel tank. According to one embodiment, the fuel level sender unit supplies fuel level information to both a dashboard-mounted gauge and the cap-proximate fuel indicator. A switch supplies power to the cap-proximate fuel indicator and the fuel level sender unit, without powering on other watercraft systems.

The fuel level indicating apparatus of claim 1 further comprising a switch operable to a closed or an open state and responsive to the power supply for switchably supplying power to the fuel level detector and the fuel level indicator in response to operator operation of the switch to the closed state. 3. The fuel level indicating apparatus of claim 2 wherein the vehicle further comprises a plurality of systems operable in response to the power supply, and wherein the switch supplies power only to the fuel level detector and the fuel level indicator when in the closed state. 4. A fuel level indicating apparatus for a vehicle comprising a fuel tank and a refill orifice through which fuel is supplied to the tank, wherein the orifice is removably sealed with a cap, the indicating apparatus comprising: a fuel level detector for determining a fuel level in the tank; a power supply for supplying electrical current to the fuel level detector; and a fuel level indicator responsive to electrical current from the fuel level detector, the fuel level indicator for determining a parameter of the electrical current related to the fuel level and for displaying a fuel level indication, responsive to the parameter, that changes as fuel is supplied to the tank, the fuel level indicator for mounting proximate the cap to permit viewing of the fuel level during a refueling operation, the vehicle further comprising a dashboard and a dashboard-mounted fuel level indicator disposed therein, wherein the dashboard-mounted fuel level indicator provides fuel level information in response to the fuel level detector. 5. The fuel level indicating apparatus of claim 4 wherein the fuel level detector comprises a first and a second fuel level detector, and wherein the first fuel level detector provides fuel level information to the dashboard-mounted fuel level indicator, and wherein the second fuel level detector provides fuel level information to the fuel level indicator mounted proximate the cap. 6. The fuel level indicating apparatus of claim 1 wherein the vehicle comprises one of a boat, a plane, an automobile, a truck, a motorcycle, a railroad locomotive, a watercraft and a land-based tired vehicle. 7. The fuel level indicating apparatus of claim 1 wherein the fuel level indicator comprises an analog display or a digital display. 8. The fuel level indicating apparatus of claim 1 wherein the vehicle comprises a watercraft, and wherein the fuel level indicator and the cap are mounted in a region of a gunwale of the watercraft. 9. The fuel level indicating apparatus of claim 1 wherein the fuel level indicator displays the fuel level as a number of gallons remaining in the tank or as a percentage of tank capacity. 10. An apparatus for a vehicle comprising a fuel tank and a refill orifice through which fuel is supplied to the fuel tank, wherein the refill orifice is removably sealed with a cap, the apparatus comprising: a fuel level detector for determining a fuel level in the tank; a battery; a fuel gauge disposed for operator viewing of the fuel level while operating the vehicle and for displaying a tank fuel level during vehicle operation; a fuel level indicator for mounting proximate the cap to permit viewing of the fuel level during a refueling operation; a switch; an electronics module; wherein a first battery terminal is electrically connected to a first indicator terminal through the switch; wherein a second battery terminal is electrically connected to a second indicator terminal, to a first detector terminal and to a first fuel gauge terminal; and wherein a third indicator terminal, a second fuel gauge terminal and a second detector terminal are electrically connected to the electronics module. 11. The apparatus of claim 10 wherein the electronics module produces a first signal supplied to the fuel gauge for indicating a fuel level in the fuel tank and a second signal supplied to the fuel level indicator for indicating a fuel level in the fuel tank in response to a closed state of the switch. 12. The apparatus of claim 10 wherein the electronics module produces a third signal supplied to the fuel level indicator for indicating a battery voltage. 13. The apparatus of claim 10 wherein the electronics module produces a fourth signal supplied to the fuel indicator for indicating a fuel level in the fuel tank as a percentage of fuel tank capacity. 14. The apparatus of claim 10 wherein the vehicle comprises one of a boat, a plane, an automobile, a truck, a motorcycle, a railroad locomotive, a watercraft and a land-based tired vehicle. 15. An apparatus for a vehicle comprising a fuel tank and a refill orifice through which fuel is supplied to the fuel tank, wherein the refill orifice is removably sealed with a cap, the apparatus comprising: a first fuel level detector for determining a fuel level in the tank; a second fuel level detector for determining the fuel level in the tank; a battery; a fuel gauge disposed for operator viewing while operating the vehicle and for displaying a tank fuel level during vehicle operation; and a fuel level indicator disposed proximate the cap to permit viewing of the fuel level during a refueling operation, a switch; wherein a first battery terminal is electrically connected to a first indicator terminal through the switch; wherein a second battery terminal is electrically connected to a second indicator terminal, to a first terminal of the first detector, to a first terminal of the second detector and to a first fuel gauge terminal; wherein a third indicator terminal is electrically connected to a second terminal of the first detector; and wherein a second fuel gauge terminal is electrically connected to a second terminal of the second detector. 16. The fuel level indicating apparatus of claim 15 wherein operation of the switch to a closed state activates the fuel level indicator for displaying the tank fuel level. 17.
