Where & How to Tee into Webasto Aux Heater Fuel Line?

[1Pearman]

As per title I’m about to order a eBay night heater. I’ve got a webasto aux heater so want to tap into the fuel line for that with a tee piece. However I’ve also got an adblue tank right in the way of the pipe work and I don’t want to mess around with dropping it.

The below images show the available pipe before the fuel pump. As far as I can see this rubber connector piece is the only bit I have available to put a tee piece in, but I can’t find any info on it to see what size tee I need. Anyone got any ideas what I need?
Cheers

Does your Webasto not operate as a night heater? I have one which I can set up to run for predetermined periods and controlled by the thermostat.

No, I believe you can buy some extra parts and reflash the heater ecu, but looking around it’s 4/5 times the cost of fitting a £100 heater from eBay. I also couldn’t find any info on whether doing as you suggested then means the aux heater won’t preheat the coolant as it’s designed to do and only operated as a night heater.

@oldiebut goodie is the guru on here for all things to do with heaters. Mine does programmed heating and hot water, but I can't operate it remotely to warm up the van before starting it (I don't think?). I might be able to add a controller to do this but I suspect it's probably quite pricey for something I wouldn't use regularly. If I lived in colder climes and used the van as a daily drive however, I'm sure it would be a must-have.

good evening
in the end this pipe seems to me the most convenient place to put the T for those who have a water heater.
Confirm?
Thank you

For me with an adblue tank then it seems the only accessible pipe to tee without dropping the adblue tank and assembly. It also looks fairly simple because it’s a rubber joiner piece so can be removed and cut to fit the tee with no extra parts needed.
If you don’t have an adblue tank then perhaps there’s some pipe work between the fuel tank and your heater that would be easier?
