the nozzle is free of obstruction;

A primary fuel filter is installed on the engine.
This filter may consist of a filter cartridge with a
drain valve at the bottom, or a filter cartridge, a
water separation bowl and may have a fuel

entering the fuel system. The primary fuel filter
should be drained periodically or when the

loosen the drain valve below the separator.
