Thread: Long Range tank for my Disco

What sort of range do you want? 2 jerry cans and a main tank will easily see 1000km in a Tdi, and will only cost about $50.00

I have a pair of sill tanks if you want them,(1 stainless water tank, 1 steel fuel tank) BUT, they aren't on my vehicle because they hang down below the sills a fair bit

FWIW, Longranger tanks are very well made, I have a 136litre one in my RR, and it has supported the weight of the vehicle on a few occasions and no leaks..

Ive got a 135ltr Browndavis tank and I have a rear swaybar

I get well over 1000kms out of it on a Hwy run and I havnt been anywhere off road for a far enough to see what I get off road but city driving the nworst I have got is 840kms from full.

I was getting much better before the lift and the bigger tyres, when we did Alice springs trip it was still on standard suspention and 28" tyres and heavilly loaded we got no less than 13ltr/100kms at 130kmh in the NT and sitting on a steady 110kmh most of the time in Vic and SA I averaged in the 9's, (ive got it written on the map we took but thats been filed away).

The issue I have with Gerry cans is that they take up a lot of room either inside the cargo area or on the rack making the vehical more unstable.

Failing that you have to put them on the back so that means you need a neew rear bar and gerry/wheel carrier and thats really pricey.

I have had 2 gerrys of water, a spare tyre and the RTT on the roof which is much more than what should be up there and it did wave around in the breeze a bit but still drivable but I wouldnt recomend it or be looking forward to doing it again.

Diesel, No worries

From what I got out of that is he wants to put the LPG inside the car.......and thats no probs as long as it can be vented to the outside which means you end up with big holes in the floor which let in water.

So I would say, no probs as long as you dont go through water.

Sorry just reread it and see what you mean.

As long as it is properly mounted and vented as well as double skinned then it shouldnt be a problem but it would have to be engineered I'd be thinking .

I haven't seen the BD tanks in the flesh before, all the ones I've seen are the longrangers, I have one in my RRC, and all the D1's I have seen have the sway bar brackets removed to fit their bigger tanks.

I have seen a Longranger in a 130 that has provision to have the sway bar refitted, but it lowers the departure clearance a LOT

The way I see....if you want to extend the range of your car between fill ups there is only one option....... sill tanks.
They increase your capacity by nearly twice the ammount.
They don't affect your departure angle.
You can retain the rear sway bar so handling isn't compremised.
They keep the COG down low compared to internally stored or roof mounted jerry cans.

Minus points.
Initial Cost.
Filling them is slow compared to other storage methods especially if you have the filler under the arches.
Transfer rate of fuel was painfully slow. But I have now fitted two higher speed Facet pumps which are twice as quick.
They don't always have a guage to monitor the fuel level. I plan to correct this soon by way of adding two floats and a dash mounted guage.
Whilst the tanks are out for fitting the floats I will also add an additional side filler so I don't have to use the under arch system on one of the tanks.

I've also got a Brown Davis tank. My old man and I both bought one each for our initial trip, mine went into the defender and his into Disco 1. I had no dramas with the Defender (129ltr) same as the disco (which I now own). The tanks went in fairly easily. They don't seem to effect dep. angle too much, however I don't really do anything too hard core just a mix of highway and dirt ks. I would not hesitate getting a long range tank again, the choice I guess is where you get it from.

The departure angle is the same as the original tank and original sway bar mountings.

The difference is that the sway bar mounts are brought down by about 2" by a piece of 2"x1" RHS and some flat with some holes drilled in it and the tank goes nearly right up to the floor with a cut out for the float and fuel pick up and filler etc.

The bottom of the tank is like wings that fit under the chassis rails but not really much lower than the original tank and is tapered off at the rear of the tank to allow for the departure angle.

Now I have crunched the tank once but a Disco with a similar set up to mine but wityh standard tank also hit the same rock and on a trip with Rangieman and Sschmez I crushed the swaybar mounts but then again, so did Sschmez and he's got a standard set up so I see bugger if any difference.

If you like JC I can take some pics of my now bent and bruised tank and swaybar mounts.

By the way, I got it as a fluke, I was ringing around all the people I could think of looking for any sort of long range tank, sill tanks or replacement and got this one from AMV second hand.

It bolted up to all the standard mounting points and the pick up and everything is standard and still screws in with the big nut thingy in the top of the tank so fitting was a piece of P***.

I have the Long Ranger which was fitted when bought so no real cost to me and I love it. Brilliant range! No problems so far...well only the fuel pump, but that's age not anything else...
Cheers

You can fit sway bars with the Long Ranger in the D1 and it does not affect departure, and that goes for all of them from day one, sway bar runs just under tank and and is close enough behind the rear axle to not be a problem as the tank barely hangs any lower than the original, don't need sway bars anyway i've taken mine off. Mine were the very first tanks made for the D1 and it's seen 350k very strong tanks you won't have any problems with it.
You can also get them for the Defender, lots of choices there depending on model.
