4 Fuel Systems

Fig 22 – Sample fuel system layout with Webasto 12L plastic fuel and vehicle fuel tank.
For caravans, Webasto can supply a 12L plastic fuel tank with sight level gauge and a quick connect for the fuel line.
With Motorhomes, fuel can be sourced out of the vehicle's own fuel tank via a fuel pick up supplied with the kit.
Note: When sourcing fuel from vehicle's fuel tank, do not cut into the return or supply line for two reasons:
1. Latest model vehicles have highly pressurized fuel systems.
2. If you perform any modifications to the vehicle, you may void the vehicle warranty.
Ensure that the clamps are tight on the fuel filter and the fuel pump and follow the direction of the flow as shown by
arrows on the fuel filter and the fuel pump for correct operation. The fuel lines can be protected in conduit and cable
ties to secure; these are not supplied in the kit.
4.1 Installation – Fuel Pump
Ensure that the fuel pump is installed with the clamp, 90
This will reduce resonation through the vehicle. (Fig 23)
