Scotland 2012 Defender 110 Puma 2.2 SW Orkney Grey
Auxiliary Wheel Arch Fuel and Water Tanks
I am making the list of things to do to our puma 110 7 seat station wagon to make it a basic overland vehicle.

The plan is to fit auxiliary tanks in the rear wheel arches but I was wondering about if they would block access to the rearmost nut for removing/replacing the third row seats?

These seats are would not be needed when in overland mode but would be required for family bus mode and we regularly have them in and out at ‘short’ notice.

Has anyone else come up with a solution for this other than not fitting the rear nut each time?

Steel M8 Rivnut perhaps ? That's how the front seats are held in. The Land Rover part is a larger hole diameter than general use ones, not sure why. http://www.yorkshireoffroadclub.net/

Riv-nut wouldn't work, I had thought about welding a nut to the underside but then realised the bolt is not turn able from the topside as it is welded to the seat bracket. I guess this is so you can fit the seat singlehandedly.

The image attached shows one of the front brackets with its bolt.

Remove the welded bolt, drill out and replace with a removable one and stick with the welded nut idea underneath. I don't think a rivnut may be such a good idea unless you form a washer underneath when compressing for extra strength perhaps? If you go through life with your head in the sand....all people will see is an ar5e!!

Treat every day as if it is your last....one day you will be right!!

The main problem you will have is to fit the tank in the back wing you will have to remove the brace that connects your rearmost seatbelt to the chassis. It usually quite a tight fit and as the brace is a tube it is too large. Unless you can get a replacement in flat bar made.

As pointed out you may have issues with the seat belt mounts.

Personally I think you will have major problems as the fuel wing tank basically fills the whole of the back of the rear wheel arch.

Best way of confirming this is have a quick chat with Tom at Safari Equip who makes the tanks on 01274 835500

Modifying a Defender is always full of compromises

Lets go back to basics. What range are you looking to achieve?

A replacement main tank will hold 120 litres of fuel which will give a possible range of 600-700 miles. This is only about 10 litres less then standard tank and a wing tank. Now no aftermarket tank guard will work with a replacement 120 litre tank, so if you want to protect the tank it can be double 'bottomed'. Next the standard towing equipment will not work with a 120 litre replacement tank. So if you also tow you will have to change your tow set up.

Water tank will have same issue as fuel tank. Consider 2 x 20 litre Swiss water bladders. Have some advantages as they are cheaper then a water tank and you can take the bladders to the water source rather then trying to get your vehicle to the water source.

We can supply the tanks and towing equipment . If you want us to give you some ideas on prices drop me an email.

You can get a 40ltr water tank that fits along the edge of the chassy under the drivers side as supplied by dormobile ..
i've one fitted for years and have no problems offroad as its moulded to with within the wagons profile.
As seen on the attached picure that I had taken just to show the tank location ...... Whistle

Safari Equip do cill tanks as well. If I remember correctly on their 'standard' tanks SE can provide 330 litres of fuel.

With cill tanks you will require switch over valves and extra pumps so is more complicated then a straight flow through wing tank which gravity feeds into the main tank.

Like many things with modifying Defenders decisions and compromises have to be made.

On our 110's we have wing tanks fitted, and one also has a 120 litre main tank which gives it an incredible range with 170 litres of fuel. When driving the 90 on standard fuel tank seem to be filling it up quite frequently.

Thanks for all the tips particularly Brendan.

I think my initial problem with the seat can be fixed as suggest cutting the bolt off and riveting a nut similar to this:


I am looking to get a range of around 500 miles. Changing the main tank and towbar will be way outside my budget.

Searching the net it looks like the front runner and britpart post 2007 aux wing tanks come with flat brackets to replace the seatbelt tubular bracket. Once I get budget approval from her indoors will give safari equip a call first though.

The swiss water bladders look just the ticket for water and I guess can be used for solar heating of water. Also means I would only need to modify one seat!

Where are you thinking of going?

A range of 500 miles? Working on 5 miles/litre or 22.5 mpg then that requires about 100 litres of fuel. Standard 110 fuel tank is about 75 litres which should give a minimum range of 375 miles. A 20 litre jerry/fuel can would give another 100 miles. Two 20 litre jerry cans should give you a 500 mile range with fuel to spare.


A couple of 20 litre jerry cans would be about £ 50, a couple of 20 litre Swiss army water tanks about £45.

Depending on what fuel tank, what material, double skinned etc you could be paying 10 times the price of a couple of jerry cans. Plus time/money to have it installed.

Have travelled a fair distance with jerry cans in the back of a 110 as long as they have good seals on, not overfilled, securely fastened down etc have not experienced any issues with carrying them on the inside of a 110. OK there are various rules concerning amount of extra fuel you can carry on ferries and what you can carry across international borders.

A couple of fuel and water tanks could cost thick end of a grand. a couple of bladders and jerry cans a hundred quid.

So consider where you are going, distance between fuel stations, how you are travelling, solo vehicle or in a group, what your anticipated fuel consumption would be etc. Fuelling up at every opportunity etc is good practise.

Have come across people who have run out of fuel 20 miles from a fuel station, because they did not fuel up at the last station as the next one was 5 cents a litre cheaper. Spending a couple of extra quid on fuel would have saved them a lot of grief.

Keep us posted on progress as I am in the same boat. I sold my Toyota Prado which had two 90 lt tanks and the small defender tank is perhaps the only gripe I have with the car. I wish LR gave you a factory option for auxiliary tanks. Oh well. We can't have everything!

I'm with you there East Freo, my Prado was the same but a bit of price pain at the pump if you let it run down low. Sad
I now go with a couple of jerries rather than pay out a couple of grand for a replacement tank and the different tow bar necessary when you change tanks. I have got a wing tank though.
I tend to fill up at any of the big servos rather than try for a few cents off and anyway in the bush there isn't a lot of choice. Fill up or walk a bloody long way.......

Hi AlanH. I see you are in WA. Where did you get your wing tank fitted? Any recommendations?
Cheers

Hello EF. I had mine done at OL in Wangara but after taking it out once I think I'd do it myself if fitting another anytime. Certainly not difficult to do.
I may get a water tank for the other side and will fit that myself.
Cheers.
AlanH.
