Sorry for the dumb question but why are you using a portable tank for the Webasto?
There’s a reputable set of products to do the above made by Power Service:There is a typical anti-jell (pre-treatment)and also a fuel line anti freeze (fix frozen/blocked lines) that you add by removing the fuel filter and filling it with the treatment.
I used to work for a large National crane hire company all the mobile cranes that had Ebespacher's fitted were converted to run on Kerosene to reduce the chance of fuel waxing. Not that we encountered the extreme cold temperatures in the UK that are the norm in some countries.I also have the information that I can add petrol to the diesel to stop it waxing. Not sure how the Eberspacher will like it. I c9ntacted Eberspacher once about adding anti Waxing agents the fuel and received the stock non informative answer " don't " without further explanation
I think this is their safe answer.
All of this is another reason to make be think that a dedicated heater fuel tank from within the warmer area 9f the vehicle could e a good choice.
Luckily I should not hit the tempreture you speak of of until the upper part of north America in a good few years
Once you get the engine running then your almost home and dry as the 0ump will return warm unused fuel to the tank
