Fuel system components Manual Instructions Extract:

Fuel Flow

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.
