4.2 Installation of Fuel Stand Pipe
When fuel is sourced out of the vehicle's fuel tank, ensure that the stand pipe is installed on a flat surface and cut
the stand pipe length so that it is 25mm from the bottom of the tank. See Fig 21/22.
Fig 21 – Installing fuel extracting device – (Top Mount type)
Install the tank extracting device as shown Fig 21
Shorten the immersion tube; the end should be approx. 25 mm off the bottom of the tank. Cut the tube diagonally
and ensure you deburr the cut edges. (Fig21)
Drill a 25mm hole on the flat surface of the tank (Fig 22). Ensure you grease the drill bit and drilling surface or apply
masking tape beforehand (to catch small drilling chips or swarf entering the fuel tank).
Install the fuel pick up and tighten the locking nut (the seal should be slightly compressed; applying any locking glue
will be advisable).
4.3 Fuel Filter
To ensure a clean combustion process, a fuel filter is supplied. Always check the direction of flow as marked on the
filter (Fig 23). The filter should be installed between the fuel source and the fuel pump.
Do not substitute the Webasto supplied fuel filter with non Webasto replacement.
