8.5.2. Installation and attachment
The metering pump must be secured with a vibration-damping
mounting. Its installation position is limited as shown in Figures 15
and 16 in order to ensure effective automatic bleeding.
As a result of the risk of corrosion, only genuine Webasto parts may be
used for the plug connections between the metering pump and the
metering pump wiring harness.
8.6. Fuel filter
Only a Webasto filter, order no. 487 171, is allowed to be used if the fuel
is expected to be contaminated. Install vertically if possible, however at
least horizontally (check flow direction).
