For occasional use, 3 jerry-cans, filled outside the vehicle, strapped to the back of the cargo barrier.

Pretty sure mines the BD with no pump involved. Can't remember how much it holds exactly, but being gravity fed means no pump to worry about of course.
So one of my original questions when trying to work out which brand to get was the pump issue, "do I want potential problems out in the middle of nowhere, etc etc etc,,, remembering to transfer, how much you transfer,, yada yada yada". Yeah I know, all hypothetical of course, and also, there's always some sort of fix.
I had the choice taken away from me at the time of fitment due to where we got it fitted, so I ended up with the BD.

So, my only issues are,, No gauge to see how much is in the aux tank, (at a glance) and no way of separating the two if I should stake/damage one of the tanks. ( there always seems to flaws in each scenario ). The only other issue I have seems to be at filling time. Not sure why, but it takes forever to fill due to fluid coming out of the breather. Don't know if this is just my tank, or the tank set-up full stop. Keen to hear what issue anyone else may have with this, and if there is a fix (??).
So, a couple of runs with both tanks full, to see an approximation of klms covered between tanks gives one a general idea of time/distance, although not perfect as I didn't really do this when I first bought the car with its original tank,,, was a bit eager to just drive it .

Ultimately, there's no problems, other than the gauge. I "doubt" I'll drive it rough enough to damage the tank,,,, but then thats why they call them accidents,, one just never "knows".
I hope to remove it all and fit a gauge to the aux at some point in the future, and at the same time, place a tap of some description between the two,, but we'll see.
But now I have to do my numbers all over again for the right knowledge when towing.

I have the 104 ltr tank with the transfer pump which pumps 2 ltrs per minute I run the pump at 10 minute intervals so I roughy how much is left in the tank. And the gauge is above the the LH sig.lighter

The only other consideration in my mind is the size of the tank. Anything above 100 odd litres will hang lower than the spare tyre and will be prone to damage. I've got an Outback Accessories 92l tank and it makes the departure angle a little better. It's gravity feed and some don't like that. All up I've got 175l and that's good for 1500km on road.

In reply to Tombie's query re securing bladder. The bladder has 3 ratchet tie downs which loop through buckles secured under front and rear seat mounts and pass thru vinyl sleeves which are moulded in to bladder. Very secure and never moves and is easy to remove when not needed. They also make one to fit in well if third row seats are removed but this would throw more weight to rear.

I’m more concerned how you anchor a flexible bladder on the floor of a D4.

There are very few points to pick up and the bladders I have seen have very little to support them as you describe requiring lashing to decks etc.

Having a good look in the floor of my D4. There is insufficient suitably rated lashing points to prevent a 120kg missile taking off.

Hi all
I have a D3 but i think the D4 is the same. Has anyone explored the possibility of using the volume on the RH side of the car which mirrors the left hand air tank and air compressor?

I have made some back of the envelope calculations and it seems that about 30 litres would be easy and quite a bit more with a more complex shape.

That is a lot less fuel than the others but just pushing the van towing range out to a very safe 500k would be useful for me. Weight is in the right place too. If it could be plumbed in so that it just appears like you have a slightly larger main tank that would be good.

Probably too expensive for the gain made, anyway just a thought.

BOAB Poly Diesel Fuel Tank 50 Litre Ute Tray or Wagon Floor Mounting FTP50T | eBay

Could secure to tie downs and probably child seat anchor points on back of seats...
Admittedly that only gives me an extra 50l but that is most likely enough for most trips we might do. And I can take it out when I don’t need it around town.

Interested in people’s opinions...

If you have a 5 seated there is a large void in behind the rear seat under the floor which would be perfect for it. Although I do intend to use mine for a water bladder.

Hi David. I have considered something like this also. There are also a huge variety of boat plastic fuel tanks available in any manner of shapes and capacities (up to 120l).
