The reservoirs with pumps and immersion
tube senders rest on and are clipped to the
bottom of the tank. Flanged covers provide
access to the components.
Single-stage pumps are used for diesel
engines (Common Rail). On account of the
higher viscosity of diesel fuel, pre-delivery
(extraction from bottom of tank) is not
implemented by way of separate pump units,
but rather by suction jet pumps.
Two-stage fuel pumps
The two fuel pumps (petrol engine) are of the
two-stage flow type.
The first stage (pre-stage) pump unit draws in
fuel from the bottom of the tank and conveys
it into the reservoir. This ensures that even
small residual quantities can be transported.
The second stage (main stage) pump unit
draws in fuel directly from the reservoir.
