It is a filter in the fuel line to screens out rust particles and dirt from the fuel. If i remember correctly, according to Kah Motor they list it in the major servicings (every 40000KM) siss and bros out there pls correct me if wrong, thanks
sometimes when i apply the throttle, the feeling is something "choke, petrol not feeding". IS this sympton fuel pump or fuel filter ?? i have difficulty starting car on cold mornings, crank is strong but difficult to start.
