I installed my Long Range Automotive 30 gallon auxiliary tank last week that I had imported from Australia. It took a good 8 hours from start to finish. I now have 50+ gallons of fuel onboard that should give me about 800-900 miles of range.

The single port factory filler neck is replaced by a twin filler neck. The front hole is the main tank and the rear hole is the aux tank. I mounted the aux tank gauge/transfer switch in the secondary lighter hole on the dash. When your main tank gets low you hit the button and it transfers fuel from the auxiliary tank to the main tank while you drive. Pretty neat! It was a bit more of an involved install that I thought- Theres quite a few holes to drill in the frame and I had to cut and graft parts of the factory vapor lines onto the filler neck supplied with the tank (I'm not sure if emissions in Australia are different). All in all though it wasn't too difficult but the instructions could have been better.

The tank itself is pretty hefty steel and the welds look great. I'd say it weighs well over 100 pounds empty.

I just ordered a Hitchgate Solo (the high clearance version) to mount the spare on the back. Hopefully It'll look okay!

Long Range Automotive has a diesel version of this tank on their website, however I'm not sure if anything is different with the diesel version of the WK here in the US (DEF tank?) vs the exported WH diesel.

I ended up doing a similar thing with mine as was fed up with the terrible range. I've got a second tank but can physically switch between which one I want to use. Looks like a tidy install you've done there so good work. Spare for me now lives on the roof which is entertaining getting it on & off since I've lifted it lol

No, It was just shipped sea freight to Philadelphia and then taken to a warehouse. Logistics Plus was the company that handled the freight and importatation.

I looked at this a couple years ago, there was even a thread about it:
http://www.jeepforum.com/forum/f67/gas-tank-relocation-3388058/

It really does look beautiful. OP, why didn't you have it powder coated or painted? Also, are you confident on the new tank's ability to withstand rock impacts if you wheel this thing?

Personally, I'm looking for a ~1999 era XJ fuel tank assembly to install in the same location. Only 20 gallons of extra fuel, but perhaps 1/4 the cost of this thing.

For the record, the spare tire slot on these jeeps measures 36"x24"x16". An 1999 Jeep XJ fuel tank measures 31"x21"x12" and you can buy a pretty beefy 1/4" plate steel skid for it.

Perhaps a local fabricator like UCF or JBA could buy the prints from LRA and produce one locally? Also, I wonder how much shipping and customs would fall if a group buy of 20 were made? I imagine you could stack five per pallet and move in a C-Can or something. Get that price down to $1200-1300 USD total and people would buy them.

It is painted silver from LRA. JBA (4xGuard) is right down the road from me, so I'll probably visit him and ask if he can make me one of his Rear Guards without the semicircular cutout for the spare tire and have it extended a little bit.

It would be nice if there was a U.S. reseller... but there is not.

30.5 Gallon capacity
Tank is made of 1/8" thick Aluminum alloy and TIG welded.
Includes a*heavy duty 3/16" thick Skid Plate.
There is a*foam liner in-between the tank and skid plate.
Stainless steel straps hold the tank in the skid plate.
Multiple internal baffles to reduce fuel movement & keep fuel near the pick up.
Uses*the newer style stock Jeep XJ*fuel module (pump/sending unit) 1997-2001.
Works with the factory*emissions*and other related equipment so you will not get any check engine lights or other engine computer issues.
Ground clearance is the same as stock or slightly lower depending on the model year Jeep you have.
Includes two new factory Mopar roll over / vent valves.
Patent Pending.
Of course, one would still need to:
Fabricate mounting brackets
Procure a Transfer Pump like this https://www.amazon.com/dp/B00L6DGHCK/_encoding=UTF8?coliid=I2EEMSFMELR42I&colid=1SNTNZ7TLIDL0
Produce some sort of timer to limit the amount of fuel transferred.

The Titan aux fuel pump systems transfer about 5 gallons of fuel per button click over 10 minutes I believe. When I spoke with them about buying just their electronics package they initially gave me a price of $150, but then decided they didn't want to sell parts separately. So, keep the price in mind for what the LRA kit provides considering what you have to make on your own to use a locally produced tank.

Has anyone seen more rectangular aftermarket fuel tanks available? The gas WK's have a muffler on the passenger side, but on the diesel it's just a straight piece of exhaust running down there. If the exhaust was moved to the side a bit more I measured that a decently large tank would fit over there. Being conservative I think my measurements said an extra 45L/12gal could go over there. It's not as much as the big rear tanks but then the spare tire doesn't end up homeless.

At least for the gas guys, if you took the stock tank and skid plate out of an XJ I would imagine you could use the stock fuel level sender and pump as well. It would be easy enough to hook those to some LED's to indicate level and a switch for running the pump. I know the WJ skid fits on the XJ tank, I'm not sure if the WJ tank is any bigger but if you got one from a V8 I'd guess the fuel pump would be more powerful.

My last extra tank I had was made by TransferFlow.com
https://www.transferflow.com/

They don't have a setup for these WK's but their system is the best I've seen and used. It automatically transfers fuel between the tanks.
It monitors the fuel level on both tanks, and transfers fuel from the aux to the main when the main reaches a set level. It refills the main to a set level.

I like the system from Long Range Automotive. It couldn't be easier.

When your main tank gets low, push the fuel transfer button. When your main tank is getting full, push the button again to stop transferring fuel. I like being in control of it all... its neat.

If it slips your mind that you've hit the transfer button, or some idiot messes with it, what happens? Does the extra fuel fill your canister and cause some kind of problem, or does it pour out of some overflow, or? Not that gas on the ground is safe, but it happens a lot and doesn't usually catch fire.

If you let your main tank run out, which I wouldn't do on purpose, does the WK hemi have trouble re-priming? I've heard of vehicles that just about need a mechanic after you run out of gas, but haven't seen it (the last time I ran out of gas was 1985, and that was a motorcycle).

I'll PM him, but anyone figure out if LRA has a kit for WK? I only see WH.... Would it be same kit? Don't know if anything is different down there on the Euro model?



and.... my membership expired bc i can never remember my password lol
