Fuel Tank Capacity

[TamsTJ]

Hi, I'm looking to increase the capacity of my fuel tank. Has any one have any experience with either a replacement or auxiliary tank. My 98 TJ has a 2-inch body & 4-inch suspension lift.

Any comments, or details of manufacturer appreciated.

[zzzz]

you can get another auxilary tank fitted to the TJ. Behind the tcase and next to the drive shaft between the frame rails. Someone has had one installed on the board and they will chime in I am sure.

Now, where in Melb?
What are the exact specs of your jeep?

i have an aux tank from long range automotive in Lilydale. Cost $850 plus around 450 for them to fit. sits infront of the pax side rear axle. It is a 45 l capacity and works quite well. Although sometimes the pump takes a while to transfer. need to look into why. Reasonably easy to install as long as you know what you are doing as the instructions are pretty crap.

Cool, could you do us a favour next time you are under your Jeep and measure the height of the tank at the leading edge. How far from the floor pan to the bottom of the tank? LRA are meant to be faxing me the dimensions but haven't seen them yet.

Matt,

Will do. What I can tell you is that it is flush with the transfer case plate. However, I have transfer case spacers installed with my OME but no body lift. so not sure if it would be any different if you didn't.

pax side front edge sticks out a little (sideways not down) from the trasfer place which I am a little concerned about but once I get a body lift it should be hidden by the chassis I hope.

Thanks, is the tank from LRA a standard item, or was it custom built for you. The Teraflex long arm kit may be a small problem, but sounds like LRA may be worth chating too.

Has the tank affected you ground clearance, or ramp over angle at all. Like MattC, the dimensions are interest to me.

Exact Spec of Jeep
TJ 98, Manual, Soft Top, Red.
4+ inch suspension lift. Just installed teraflex long arm kit (control arms), much nicer ride now.

was wondering when/where that would show up.

Look forward to going out for a drive with you some time.

the tank is a standard item but they don't list it on their web page. As Mattc said they can fax you the instructions and dimensions. Doesn't reduce my ramp over angle any more but my tansfer case has been dropped to fit my OME suspension as I don't have a body lift at this stage.

[TamsTJ]

Yeah, I phoned G&J Gear to get some pricing information for a White TJ 97. Ended up buying his modified TJ. Had a bit work done on it to make it more road friendly (USA 4x4). Compared to our old TJ, this thing rocks. It was previously moved in a trailer to events, but we intend to drive it more. Hence the requirment for a new fuel tank and some road manners.

Try calling Mick at Suburban 4x4 in Sydney he should be able to give you the excact details but as far as I know there can be a clearence issue with a TJ and LRA tank if you have big lifts and in particular long arm kits but he should be able to give you the exact details he has built Jumbos TJ and it has a LRA tanks and is far from stock smile.gif

I believe that LRA also do a replacement fuel tank aswell that holds about 110 to 120 lt. Alan Mcmullen has one in the back of his tj.

Long Range are closed over Xmas. Each tank is custom built, so allow several weeks from ordering to delivery. I was told some time late febuary when I enquired 23 Dec.

[Ando]

Mmmmm....that's interesting. They made up my tank for me within a week. I didn't know about the replacement tank. I wonder how that fits. One benefit of an aux tank is that if you by chance punture one you still have the other.

[mattc]

OK I have a fax of the LRA Aux tank dimensions....at my Canberra desk....and I'm in Korea. For those who are interested I'll post the info Monday.

[Ando]

Matt,

The height of the tank at the leading edge is 22.3cm.

Hope that helps.

[mattc]

Thanks Ando!

I've been in contact with Brown Davis, who can build a replacement tank for around $1100-$1200 fully installed. They will need the jeep for 1 week, as the tank is custom built to suit suspension and body lift configuration. They expect the capacity to be between 105 & 125 litres. With the 2-inch body lift, it was calculated that around 20 lt could be built into the cavity alone. They pointed out an advatnage of the replacement tank is only having 1 filler point, and no pump required to transfer fuel between tanks.

Has any one heard anything about Brown Davis tanks, good or bad?.

It sounds like the replacement tank is your only option - I used to have the LRA one but long arm kits of any description are incompatible with the LRA tank. The LRA tank will sit exactly in the space where your new upper control arms sit.

If I read wrong and you don't have a long arm kit make sure that you give LRA the exct year model - there was a balacing arm added to the drive shaft (I think that's it) after 98 - we had to get the tank that LRA templated on a 98 model slightly modified to fit on my 2001 model.

My LRA tank on a TJ with 33's, 3 in suspension and 1 in body was good for about 900kms on the highway.
