A fuel tank used for a general-purpose engine comprises a hollow tank body for storing fuel and a filter disposed within the tank body. The tank body has a bottom with a trap having an internal surface portion lying in a first plane. The filter comprises a tubular body extending from the internal surface portion of the trap and a fluororesin element supported by the tubular body so that a main surface of the fluororesin element lies in a second plane disposed at an angle of inclination relative to the first plane. The fluororesin element has a property of not allowing water to pass therethrough but allowing fuel to pass therethrough.

What is claimed is: 1. A fuel tank used for a general-purpose engine, the fuel tank comprising: a hollow tank body for storing fuel, the tank body having a bottom with a trap having an internal surface portion lying in a first plane; and a filter disposed within the tank body and comprising a fluororesin element having a property of not allowing water to pass therethrough but allowing fuel to pass therethrough, the fluororesin element having at least one main surface lying in a second plane disposed at an angle of inclination relative to the first plane; wherein the filter further comprises a tubular body supporting the fluororesin element and extending from the internal surface portion of the trap, the tubular body having first and second wall portions extending vertically to different heights from the bottom of the tank body and supporting the fluororesin element so that the at least one main surface of the fluororesin element lies in the second plane disposed at the angle of inclination relative to the first plane. 2. A fuel tank according to claim 1; wherein the second wall portion of the tubular body extends directly from the internal surface portion of the trap. 3. A fuel tank according to claim 1; wherein the tubular body is formed in one piece with the bottom of the tank body. 4. A fuel tank according to claim 1; wherein the tank body has a fuel outlet port; and wherein the tubular body is provided at an inlet of the fuel outlet port. 5. A fuel tank according to claim 4; wherein the first wall portion of the tubular body is formed in one piece with the inlet of the fuel outlet port. 6. A fuel tank according to claim 5; wherein the second wall portion of the tubular body extends directly from the internal surface portion of the trap.
