FUEL SYSTEM -- DIESEL
DIESEL FUEL SYSTEM
The diesel fuel system is made up of five basic
components which are: fuel tank, fuel water
trap-filter, fuel pump, injection pump, and injectors.
Fuel flows from the fuel tank through the fuel water
trap-filter. The water trap-filter separates water and
impurities from the fuel. From the fuel water trap-filter,
fuel is drawn through the electric fuel pump and
pumped to the injection pump. The injection pump
pressurizes and sends fuel to the injectors. The
injectors atomize and inject proper amounts of fuel
into the combustion chamber at the proper times.
Excess fuel is returned to the fuel tank through an
overflow pipe.
FUEL WATER TRAP-FILTER
The fuel water trap-filter separates water and
impurities from the fuel. It is located next to the
engine bellhousing. The bottom portion of the unit is
the water trap. The middle portion is the filter
element.
Drain the water trap of water daily. To drain the water
trap, loosen the drain knob on the bottom of the unit.
First water, then diesel fuel will drain. Tighten the
drain knob when diesel fuel appears.
Replace the fuel filter element and clean the water
trap after every 400 hours of operation.
