Fuel Filter
A fuel filter may be supplied with your heater depending on kit model and application.
If the heater kit being installed does not include a fuel filter and dirt in the fuel cannot be avoided or is expected, an
optional filter is available from Webasto. Order genuine Webasto fuel filter P/N 487171. The filter should preferably be
installed in a vertical position, where this is not possible, it may also be installed horizontally (see figure 5-11). The fuel
filter can be installed anywhere accessible between the fuel standpipe and the fuel metering pump inlet (direction of flow
to be observed) .
CAUTION
Fuel lines must be secured to the vehicle every 305 mm (12 in.) and routed away from hot exhaust components and
moving parts (drive shaft, wheels, etc.).
Fig. 5-10: Fuel Line Connection
Connect fuel line from fuel standpipe to fuel metering pump inlet and from fuel metering pump outlet to the inlet port of
the heater using supplied rubber connectors and clamps. Tie fuel line in place every 305 mm (12 in.).
Fuel line connections must be made using the couplers and clamps provided and as shown in figure 5-10.
Fuel filters should be replaced at least annually and in the case of dirty fuel,
more often. Always replace with a genuine Webasto fuel filter P/N 487171.
