12.3. Fuel extraction
For recommended fuel extraction solutions see Webasto camping cata-
logue.
1) Installation into the vehicle’s fuel line.
a)
T-junction from the fuel line to the vehicle’s engine if no feeding
pump is installed inside the tank.
b) T-junction 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 down-
wards.
2) The fuel can be taken from the vehicle’s own fuel tank or from a sep-
arate tank with a fuel extractor. See Fig. 30.
The fuel standpipe must be mounted in the fuel-tank sending unit. The
fuel-tank sending unit must be removed previously. When drilling the
hole, make sure to use a plain and even surface for proper sealing.
