6.2 Fuel feed pump
The fuel feed pump feeds fuel from the fuel tank,
passes it through the fuel filter element, and supplies it
to the fuel injection pump.
The fuel feed pump is mounted on the side of this
engine and is driven by the (eccentric) cam of the fuel
pump camshaft. It is provided with a manual priming
lever so that fuel can be supplied when the engine is
stopped.
