8.6.3.1 Installation Position
It is advantageous to mount the dosing pump in a cool
location. The ambient temperature must never exceed
+20° C during operation.
Dosing pump and fuel lines must not be installed in
locations exposed to heat radiated by hot vehicle
components (e.g. exhaust line). A heat shield is to be
provided as necessary.
8.6.3.2 Installation and Attachment
The dosing pump is to be attached with an anti-vibration
mount. The installation location is limited according to
Fig. 806 to ensure sufficient self-venting capability. Due to
the danger of corrosion only Webasto original parts may
be used for the plug connection between dosing pump
and dosing pump wiring harness.
8.6.4 Fuel Filter
If fuel contaminations are expected, only Webasto filter
order no. 487 171 may be used. The filter installation
should be vertical and never exceed horizontal (observe
direction of flow).
