Defender fuel tanks underneath
I'd like to free up space inside my 110 by removing the 160 litre ali fuel tank I have inside and putting a tank underneath somewhere on my 110.

I know I can't get a 160 litre tank underneath a defender, but does anybody have any suggestions or suppliers of tanks that can help get the maximum?

I know I can get a 90 fuel tank under the drivers seat. Or many people seemed to get 60-70 litres under one side (and a water tank on the other).

I'd like to keep them plumped in seperately as they are now.

Any suggestions or experiences to share?

Many thanks!

We have two fuel tanks in the wolf, a standard 110 tank, and a standard 90 tank, I believe, we had looked into the option of getting a larger replacement for the 90 tank, but opted against it. I also know that a larger main tank is availiabe, offering up to 40l extra.

The tanks are connected with a rotor switch allowing you to switch which tank is in use. The tanks are fuelled separately using the defender 90 and defender 110 fueling points.

I am not sure how difficult this is to set up, but I don't think it would be that hard, though ours was set up from manufacture.

Location of fuel fillers:



I don't think I have any photos of the fuel changeover switch, and I know I have none of the actual fuel tank installation. I may be able to get one for you.

Sorry I can't be more help other than to say it is very possible.

Dont Allisport do 110 side tanks ? - wouldnt be too difficult for them to do - in front of rear tyre - the space occupied by Lone Wolfs jerrycan holders - then use a couple of oe fillers. -should be able to get 60+ litres in each side easily... some supporting outriggers welded on the the chassis and some steel side bars to help protect them (a good mod anyway)

This is the route I would go with a 110 Hardtop - Im looking for a lhd 110 for a new project - I must be getting old.....needing more room.....

or as youve mentioned you can fit a rhd 90 tank to the rhs of the 110 and a lhd 90 tank to the lhs - just have to move your batteries though...

either of those should give enough range.......

LoneWolf - hows the trip going ? everything working OK ? - thats a very Nice Wolf you got - glad to see its doing what it was supposed to....

cheers.

Darrin,

Have you considered a flat tank on the floor inside the load space?

Thanks Gold Wolf - hows the canned ham supplies lasting?

I saw a Series Landy of some kind today with a filler there, and this is what Matt Savage had suggested, so certainly a reasonable option. I don't want to move the batteries, so I guess a tank under the drivers seat and perhaps another on the righthand side (if it's possible to have a double filler?) would give good capacity, but leave the vehicle badly lopsided ;-)

But I guess a water tank on the other side and a few heavy packed spares on that side would help even it out, and 80% of the time I only drive filling up the original tank on the back.

How many litres does it hold?

Roman, I really want to empty out the inside as much as possible so aren't really looking at any tank solutions to put in there. Any surely filling would have the potentail to be messy?

I like the option of a water tank on one side and a fuel tank on the other, both underneath and in front of the rear wheels. I'd have to removed my jerry can lockers but thats no big deal - so has anybody done this?? ;-)

You could fit a 90 side tank to the RH side (and lose the "toolbox" under the drivers seat) and if you didn't mind moving the battery, you could fit a second tank under the LH seat also.

that would give you 3 tanks, and you'd need a changeover tap, like the ones that AndAir make,they're a little pricey (about £160) but definately quality items. designed for aircraft they have to be to good standards.The above link shows their "duplex" tap, but i'm sure they do a triple changeover, or you could use two taps, "main or aux" and then "aux 1 and aux2"

Or get Andy at Allisport to make you an "under wing" tank for the rear wings, right at the back of the vehicle, he might even be able to get them to fit around the side jerry-can lockers you've got.
