In-Tank Fuel Filter

The filter is located on the lower end of the fuel pickup tube in
the fuel tank. It prevents dirt from entering the fuel pipe and
also stops water unless the filter is completely submerged in
the water. It is a self cleaning type, not requiring scheduled
maintenance. Excess water and sediment in the tank restricts
fuel supply to the engine, resulting in engine stop. In such a
case, the tank must be cleaned throughly.
