I am the same as Tommy, I have the 4wd systems one, but I got them to customise it after they told me it would not hang lower than the standard to fit my 50mm bodylift (Which it did, hangs down nearly 2 inches lower than the chassis now), so mine is about 180L (ish) Either way.. if you can get the 8c per litre discount from Woolies when you fill it right up, you make money.. but man it hurts to do it in one go.
So I don't think I can lift mine up like Tommy2222222220 (sorry, didnt count how many 2's) which is a pity, as I would really like to get rid of that corner that sticks down, but Tommy, would be good to see some pics of yours lifted, especially what you did with the front bracket?
If I had my options again, and this one wasnt such good value (900 including postage if I can remember, to remote WA at the time) I would prefer to have two separate tanks, just incase you stake one.... but there were not many options out there. It is nice being able to go about 1300km with no worries, with my bigger tyres etc. Hope to get more out of it soon after a bit of work.
Hope it makes sense, I am delirious with some form of flu in a jungle camp in southeast asia.. haha.
