modifying a sedan fuel tank, fuel tank mods

Folks

Since my sedan and I are doing around 180km a day a bigger fuel tank would be handy. Having to fill up every day adds an extra 10 minutes to an already long enough drive.

The time also gives me time to think.
Has anyone modded a fuel tank for more capacity?

I was thinking about cutting the back off one tank and welding on another back section to extend it further into the boot. An extra 10-15 litres would be enough.

Its not like the boot is particularly useful for losing some to a bigger tank isn't too much of am issue.

Aside from draining and filling with water before cutting any hints for welding two tanks together.

better buy a tank with the right dimensions new or build a new one,
chopping and joining and old tank is a huge hassle.

all cheaper than getting someone to make a new one somewhere
 
here is a list to choose many sizes of the RCI circle track ones
 
 
and a more comprehensive list here also but from states as well
under title RCI fuel cell

what about a cut and bolt in a coupe tank in the floor....
Do what I do and keep a couple of 20ltrs jerry cans in the boot.
I did wonder if i could fit a fuel tank in the spare wheel well and hook it up with an electric pump pushing into the original tank.
 
I did also think about a fuel cell but my initial research didnt yield a tank that would fit into the origonal hole without waste. 
 
Plus i need to consider cost. $350 on a fuel tank right now is not an ideal solution.
 
The advantage of joining tanks means i keep original bolts, fuel lines and sender. And it uses the space as intended. 
 
Ill keep looking at fuel cells and maybe the right shape at the right price will appear.

You dont want to stop and fill undestandable
however uniting 2 petrol tanks is hard work
and be prone to leaks or safety issues in time
Whats the width between the rear and height
without worrying about the speakers however
considering the boot mechanism?
 
Heres another list and also consider a lower
weight to the ground setup like a drop tank
Ive always found the wheel well a horrible
rust gathering area that needs a drop tank.

Go the LJ Torana tank although they are getting hard to find. They would fit in the wheel well and would look like a drop tank! Not sure of the capacity but would have to be bigger than std. Would a wagon tank fit in the rear quarter or is there as a reserve tank?
Original tank width is 85cm x 10cm high x 10cm wide at the widest point (botttom)
If you measure the top of the tank its onlly about 5cm wide before you start to intrude into the boot space.
 
I dont mind losing some space, but i do still use the boot for the spare wheel, jack, tools and some spares.
 
Had another trawl though ebay with the links you sent D
 
Found this unit
http://www.ebay.com.au/itm/RCI-RCI1211C-22-Gallon-83L-Poly-Circle-Track-Fuel-Cell-Size-33-x-17-x-10/321405770496?_trksid=p2045573.c100033.m2042&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20131017132637%26meid%3Dd1f4921fe104404eafe8ac0dd3422c59%26pid%3D100033%26rk%3D1%26rkt%3D4%26sd%3D321405770496
 
Its very close to fitting in under the parcel shelf as standard, but it would take up the entire boot space.
 
I think ive got a wagon fuel tank in the stash, so ill see if that fits into the wheel well as mentioned.
 
I could just use a jerry can or boat fuel tank and plumb that in with a small electric pump.
 
The solution has to be simple to use else its pointless. using a jerry can, means that I have to open the boot to fuel it and when im low, pull over and pour it into the tank. Im not that far from servos that i need the extra range, its all about convienence.
 
This sort of thing might be good

its cheap and comes with fittings. Just need a pump and im away.
 
Alternativily, I could try and mount another sedan fuel tank into the boot. Mount it hard up against the original tank and double the capacity to 60l total. That might be a winner.
 
As for space under the parcel shelf.
As the tank is a rhombus to tank advantage of all the available space, a square tank doesnet really fit very well.

Wagon would be good but another sedan tank hard up would be an awesome idea providing you have no issues filling it up from original fuel entry area, otherwise in boot filling could cause ventilation issues. unless you can make it breathe to the outside somehow. I would have thought you could fit a rectangular tank upright in there as peeps have fitted 85L gas tanks.

I didn't get time today to play with this idea at all. I spent my time replacing a blown headlight...
My father is coming up tomorrow night for me to fix his spare wheel carrier so I might get some time in the shed then to at least eyeball in a second tank and see what happens.


I wouldn't be too hard to mount a second sedan tank as I could just use flat bar to extend the original mounts and its completely removable.

As for filling from the outside, I'm thinking if I make a y-piece in the flexible hose then both tanks are filled from the same filler neck, much the same way that many Prados are.

Then its just a matter of hooking up the electric fuel pump to push the fuel over to the main tank when I get low. That's just a simple switch on the dash somewhere.

Now, for this 85 litre tank you talk of..... any pics or more info?

Actually was 80L but less than that fits for LPG
It was just the usual 80L tank secured where the usual fuel tank is
so figured you could fit a rectangular tank that is taller than it is deep

My fuel tank is about 60l.  We used 25l in 100km once so had to do something about it.  The factors limiting the size of the tank is the height of the filler tube, mine has been raised as far as possible under the original flap and the size of the boot lid.  Mark in Research.
