Fuel Supply
The fuel pump is a blocking vane-cell pump.
The blocking vanes are pressed against the
pump rotor by spring pressure. This design
enables the fuel pump to deliver fuel even
at low engine speeds. The fuel ducting system within the pump
is designed so that the rotor always
remains wetted with fuel, even if the tank
has been run dry. This makes automatic
priming possible.
