Abstract
A fuel gauge for locomotives comprises a block adapted for attachment to the locomotive fuel tank near the bottom thereof, preferably by connection with a tank drain plug. First and second chambers in the block are joined by a passage connecting the lower ends thereof and serve as a reservoir for an indicator liquid having a density greater than that of the fuel to be gauged and being immiscible with respect thereto. Valve-controlled passage means connects the interior of the tank with the upper end of the first of said chambers, permitting fuel to enter the first chamber and form an interface with said indicator liquid. A gauge glass connected with the upper end of the second of said chambers in conjunction with a gauge scale provides a visual indication of the quantity of fuel in the tank.
