Fuel Extraction - Webasto DUAL TOP RHA 100 Installation Instructions Manual

Fuel supply

12.3. Fuel extraction.

For recommended fuel extraction solutions see Webasto camping
catalogue.
1 Installation into the vehicle's fuel line.
a) T-off from the fuel line to the vehicle's engine if no feeding pump
is installed inside the tank.
b) T-off from the fuel return line to the tank, if a feeding pump is
installed in the tank.
Make sure that the fuel return line inside the tank goes nearly to
the bottom of the tank, otherwise the heater will receive no fuel
if the tank's fuel level is low.
Note:
Both options are only feasible, if the fuel pressure at the connection
point to the fuel line does not exceed the in chapter 12.1, "General"
specified values.
The line from the T-junction towards the fuel pump should run
downwards.

2 The fuel can be taken from the vehicle's own fuel tank or from a
separate tank with a fuel extractor. See Fig. 22.
Install the fuel extractor into the tank extracting device, which has to
be dismounted first. When drilling the hole, make sure to use a plain
and even surface for proper sealing.
