Clean fuel is important because there are small jets and passages in carburetors. The fuel filter is responsible for keeping the smaller contaminants in the system out of the fuel delivery components and the engine. Use this paper element in-line fuel filter on any bicycle engine kit.
The Fuel Line is made universal for any 48cc, 50cc, 66cc/80cc 2-stroke bicyle engine kit.
NOTE: To install a fuel filter, simply cut the fuel line in half and insert the filter in between.
