I had a 46ltre tank made to fit under the sill behind my side steps on my 2011 defender,a diesel transfer pump to the original filler,all up for under $600. Pat
I found this thread to be really interesting. I currently have a 2001 110 TD5 which the previous owner fitted dual under body long range tanks to. (both around the 40-45 liter mark).
On a number of outback trips I would regularly travel over 1200km without any problems (never faster than 80-90km/hour due to terrain/danger/risk/fuel efficiency). Even with sections that used low range etc with load.
What I like about the under body tanks is that the balance of the car is pretty nice when you are fully fueled and loaded all the weight is not down the rear of the car. What I do not like is that they require a fuel pump which drains the extra tanks into the main tank. I have yet to find a reliable bush-proof pump. The original owner fitted Holley Red pumps, fairly cheap and mostly reliable but the seals constantly go in them and leak diesel all over the place. It seems that they tend to bust every time I go to the outback. I then replaced them with Holley blue because they are meant to be higher flow and better quality bits. Unfortunately they have never really lived up to my expectations (of lasting 3 years with at least quarterly use). I have been told that the pumps need more regular use to keep the seals wet so they do not perish. (you may ask why I do not find another pump vendor.. that is because the mounting brackets etc all fit the holley and it's a nicely done job.. getting in and replacing the pump with something else would require new brackets and work which I didn't have the motivation for.. (btw this is not a winge about the pump's they are relatively cheap ($115 inc postage) it's really just giving some more context)
Now that I am looking at upgrading to a 2014/5 Defender I looked at the various options again and so far I couldn't find a similar product that was cost effective. I have been looking at doing the forerunner under rear arch tank as a possible substitute but it doesn't give me the millage that I have now. I like the fact that it is gravity fed after the problems that I have had with the pumps on the existing units.
Keen to know how other people have felt with the different styles of long range fuel tanks and what their experiences have been.

I am also really interested in getting some advice. Leaning as well to the front runner wide tank but want to get as much fuel on board as cost efficiently as possible.
Having gone from the 180lt Prado the standard 75 lt defender tank is a bit constraining. Really wish LR would give a factory option of long range tanks.
Whatever they replace the Defender with should have the option.
Hi Pat. I am in WA. Really appreciate knowing where you got that done?
Cheers

NSW,anyone here could do it,I'll take a photo and get my partner to post it up. Pat
There is not just cost efficiency as I found out. The other challenge is getting the fuel in and balanced so that the car does not slouch big time. Right now my under body twin tanks solve that problem perfectly. The best prices I have found so far (ringing around) was around $1800 in Sydney fitted. The forerunner fitted is about $1100.
I went the Forerunner in arch diesel and water tanks. I figured if I needed that much fuel, water would be important, and my back doesn't like Jerry Cans any more and I like a low COG
By all means get a Defender. If you get a good one, you'll be happy. If you get a bad one, you'll become a philosopher.

When full do you have much rear end sag in the suspension?
I have been told that If I put the extra ~110kg's plus a touring load the arse would be scraping on the road... In my current td5 I have polyair and would like to avoid them if I can.. (I have had to have them replaced twice in 4 years).
None that i could visually see, lets face its 110 kg or so in how much payload capacity ? I probably had another 150 kg of other camping stuff and the car was level.
I did have plans to measure before & after, but ............
OR to put it another way, thats one fat bastard in the back seat, i envisage my trips will be two persons only

Just bought a ARB 127lt fuel tank. Made by out-of-town....
I found out there are two long range fuel tanks. One is made by out of town and the other made by LRA (long range automotive)...
My discovery was made by calling LRA about the out of town fuel tank.....
I am about to install it myself. So any tips here? It seems due to the shape, the tank can collect quite a bit of water on top near the fuel pump?
And should I get some insulation tape or put some anti corrosion paint?
Should I clean the tank before install? It seems inside there are quite some weld splashes...
The sway bar extension is incredibly beefy...I wish these are the factory sway bar mount on chassis....
Thanks![]()
