T6 (2016) Euro 5, Ad Blue tank space?

Hi all
I’m about to fit a diesel heater, but would rather fit internally, I’m thinking of under the double passenger seat, intake to front & hot air out the rear.
I really don’t fancy dropping the fuel tank to fit the fuel feed, and want to fit a stand alone diesel tank (possibly also under double passenger seat).
Does anyone know if the space where the Ad Blue tank is on the T6.1 (Euro 6) is available on my T6 (Euro 5) as it seems a great solution to add a tank as it could be refilled via the fuel flap and there is a space where the Ad Blue filler would be.
Not sure if there will be a space or if the T6.1 has a smaller fuel tank to make space for the Ad Blue tank. Many thanks

I have a 2016 T6 Euro 5 with an 80L fuel tank, there is space for an Adblue tank.
However it’s way less work to drop the fuel tank than fit an Ablue tank so why create extra work, the only benefit I can see is that you could use domestic heating kerosene which is about half the price, after about 20 years it would save what the Adblue tank installation costs.
Dropping the fuel tank is easy, just wait until it’s almost empty.
 
If I was fitting my gas heater again, I’d have it fitted underneath the passenger seat (I’m EU5 too) and have the vents exit the seat base towards the passengers as opposed to towards my kitchen cupboard (camper).

These aren’t the best photos but you can see the polystyrene taking up the space the Adblue tank does, along with the space within the passenger step.

Thanks buddy, yes it’s still an option, especially as I have now seen that some vans have a “blank tube” on top of the fuel sender that can be used (with an adapter) without removing the sender unit.
I will probably still have to lower the tank to see if I’m lucky enough to have that version 🤔

Thanks Buddy, that’s really useful, I’ll have to jack mine up and remove the panel to reveal if mines the same, when you say you would do it differently given the chance, you said you would have the vent exit the base towards the passengers, do you mean the front passengers (perhaps to heat the cab first) or the rear of the front seat towards the rear passengers🤔

There are two straps supporting the tank with two bolts on each, if you remove the two outer bolts and just loosen the inner bolts the straps can stay in place under the tank which makes it easier to put back. You may find it easier to lift the van all round on blocks to give more clearance under the van.

the latter - towards the rear still.
Having the heater outlet on the pax seat (as opposed to the drivers) means it doesn’t have to clear your handbrake (if you have a timber rear seat base panel) and it’s nearer the slider which is obviously your point of cold air entry.
And if yours is a camper, it means warm air will circulate more freely and not hit the side-panel of the kitchen furniture!

Thanks buddy, yes and there is so much room under a double passenger seat, I must admit I store so much stuff under there🤔. I wonder if I should make a box or shelf around the heater so I can still store stuff in there, not sure how hot the case of a diesel heater may get.

This is exactly what I did, and it has worked perfectly, with a little modification to the outlet for the diesel heater feed. cannot remember exactly what i did. Think I did it about 6 years ago, so it is possible.:D
I 3D printed an adapter for filling so I can use a gallon can,

Thanks Nickdaw, good to know. Once I get it up on ramps and get the covers off around the tank, I’ll know better which way to go, I’ve seen AdBlue tanks for sale from around £100, so it seems do able👍
