Auxiliary tank recommendation for D4

I went the gravity feed option several years ago on my D3. The KISS principle works for me. My AUX tank drains in the main tank. I did see a funny event on the very long very steep hill (mountain climb) with the fuel gauge getting lower at an alarming rate down to 1/4 as some fuel went back the the aux tank once. Not empty and it was about one hour at 40 degrees or so UP:D

I have no gauge on my aux but with the main tank give me 500-900 odd KM range with the gauge starts to move depending on Off/On road conditions I am not at all concerned about that. Mine was from Opposite Lock and they fitted it for me.

An interesting thread. The cost is not only the extra tank but the spare wheel carrier along the way so you need to include that in your cost unless you carry two spares on the roof.

We are taking a different approach. We will be fitting a Dolium tank to a custom build sliding platform in the rear only when we need the range. Combined with three JC on the roof that will give me around 190l and I can get almost anywhere with that whilst towing our Ultimate so no problems for us.

For fuel transfer we use a special 12v transfer pump with filters and everytime we refill in the outback we use a Mr Funnel aviation grade funnel as one more safety device and that has worked extremely well for the last five years

So I take you guys are all in favor of one 😊

What you say has helped convince me that my initial thinking was correct.

Many thanks

Do you have any photos of your setup? Still trying to come to grips with the need to put in an aux tank.

Howdy and not yet as we are still in the design phase but simply put it goes like this. Remove third row seats to store recovery gear, compressor and other, hopefully, low use items, put a carpeted panel cover over this, maybe. So at this point it looks like a five seater. Fixed to the tie-downs using turnbuckles will be two 2,000kg slides onto which will be a carpet covered platform with a heap of located tie down points. Platform slides out past the rear tailgate as it will be full length to rear of second row seats. What goes on this? Fridge is the most common item we carry all the time. So that leaves the rear carrying capacity very flexible. From there if no need for the Dolium tank then a space case goes in. Or the 58l diesel tank also lashed down on the platform. If we need more storage a
mesh cage over this so we can stack other boxes on top but extremely doubtful that will be required. Second spare on the roof platform.

We are taking the approach that we want as flexible a vehicle as possible to this is a highly modular approach. We don't need permanently fixed drawers and I have no desire to keep moving them in and out and the Ulti carries pretty much all else we need for outback touring

I hope that explains it. Once the cargo barrier goes in we will take the car to Tech Trek who will do the custom build for us. My understanding is that this will be a first of as pretty much everything else I have read up on is focussed on drawers which is OK if that is what you want but as I have said not on our radar.

After having a long ranger tank transfer pump fail on the csr.....was happy to have the option of gravity feed this time. I have an OL 95 litre rear tank, and it has a non return valve so fuel will not feed back to the rear tank.

3 1/2 years and very happy.

Yes, they had a few issues with pumps.

They now provide a fully sealed unit which has been faultless.

Luckily even with a failed pump you can get fuel out and into the main tank.

Gentlemen while we are talking aux.tanks,I have a Brown Davis tank fitted and the cap that comes with it doesn't have the retaining strap attached, so I tried the fuel cap from my wife's 2012 Diesel i30 and it fits perfectly. So ordered a new cap with strap all good .Cost a bit over $35. Thanks. Kero

My OL tank is also going well after 3 1/2 yrs, although not 95ltrs anymore:cool:

Baz.

Has anyone tried one of these at all?
