Adding a Extra tank

[Chilly]

Hi All,

I am looking at getting a disco with LPG. It has a 70 litre gas tank in the boot.

I was wondering if it is possible to...


add another tank to this...beside it..and connect up. Thus giving a bigger fuel capacity and therefore range?
Make the second tank removalable. Only use it when I need too?
or the third option to fit a bigger tank?


Thanks in advance

Maybe a undersill tank?

if you remove the main fuel tank and insert a sill tank for petrol for starting you can get about another 80l worth of tank in where the original petrol tank was.

yes, you can daisy chain tanks but they do develop problems.

Dual tanks are a standard type of thing, and are often connected to the same filler. Twin tanks in the petrol hole underneath will give you 70 litres.

The twin tank set-up below was originally in D1, I refitted it to a D2 later:

The two tanks hold 52 and 71 litres respectively, and are 285mm in diameter, one is 1100mm long and the other is 1500mm long.

Triple tanks are easy enough to set up, but should have separate fillers.

Removeable tanks are a strict no-no, except on a forklift or similar machine.

Another way to extend range (by up to 20%) is to add a LPG computer running off an oxygen sensor.

cheers for that bee utey,

What is involved in that and cost?

I have seen a few doughnut tanks...would one of them replace / fit where the petrol tank fits?

I can soon make a petrol tank up and fit elsewhere.

First comment requires knowledge of what gas system is fitted. Guesstimate $200 to $400 parts cost.

Donut tanks do not fit between the rails without a big hammer. Forget them. Find a used twin gas tank and rear 1/4 petrol tank set from a wreckers or ebay. I have seen a few sets go quite cheap on ebay in the last year, I couldn't be bothered chasing them. Someone even had a cradle advertised on the forum for a while last year. They are common enough.

Go to you local gas fitter and ask to look through his tank book. You can get tanks in a scuba type set up that fit under the sills and hold around 35l a side. You must fit hydrastat valve, with multi tanks, by law.
This way you get to keep your std fuel tank and no need to fit the little pain in the bum qtr tank for your efi!!!!

Answers a question or two I have.

[bee utey]

End fill tanks (not "scuba" tanks) to fit under the sills of a D1 hold 19-20 litres of gas each and hang down a little. you would add about 80km to your range for about $600 in parts plus labour. The 35 litre ones (made for Landcruiser 100 series vehicles) would hang down like dog nuts, if they fitted at all. An expensive way to add a small amount of gas. The 19L ones are usually used in diesel gas enhancement.

This one fitted to a RRC which is similar to a D1 fitment.
