Fuel system components
The fuel system consists of the fuel tank, the fuel feed
pump, the water sedimentor, the fuel filter, the injection
pump, and the injection nozzles.
Fuel is drawn from the fuel tank by the fuel feed pump. It
passes through the water sedimentor (water particle
removal) and the fuel filter (solid particle removal) before
being delivered to the injection pump.
Precisely metered amounts of fuel are forced into each
of the injection nozzles at exact intervals to provide
efficient engine operation.
• Water sedimentor
The water sedimentor has a clear plastic body. There is
a warning line on the body. When the water level
reaches the warning line, the sedimentor must be
emptied.
Open the drain plug at the bottom of the sedimentor to
drain the water.
• Fuel filter
The fuel filter removes solid particles from the fuel.
These particles, if allowed to reach the injection nozzles,
would cause serious abrasive damage.
• Fuel feed pump
The fuel feed pump draws fuel from the fuel tank and
delivers it to the injection pump. It maintains a high
pressure in the fuel line.
An independent priming pump permits manual fuel feed
when the engine is off.
