PURPOSE: A fuel gauge using a feeder pipe is provided to display the exact amount of fuel regardless of a slope or an even road by movably installing a float to the feeder pipe for injecting fuel and indicating the increasing and decreasing amount of fuel by using the change of a resistance value to the position of the float and to reduce the number of parts and assembling time by removing an existing fuel gauge. CONSTITUTION: A fuel gauge using a feeder pipe(10) comprises two rows of grooves(12) formed in the feeder pipe for injecting fuel in the longitudinal direction with being parallel to each other; resistance wires(13a) installed to the grooves to apply power; and an annular float(11) slidingly formed to the feeder pipe and composed of brushes(15) forming contact points with each resistance wire and bridges(14) for connecting the brushes. Thus, the fuel gauge using the feeder pipe displays the amount of fuel to the position change of the float on the feeder pipe. The brush formed at the float is inserted into the groove to constrain the rotation of the float. A stopper is installed to the lower end of the feeder pipe to prevent the separation of the float.
