Has anyone fitted a LRT on a MUX  and if yes how do you find it. How is the accuracy of the fuel gage affected?

 Coop47 hi

No I do not own a Mux.

I do own a vehicle fitted with a long range tank, fitted by a large company at a cost of around $1400. Money well spent with a engineering certificate to keep it all legal.

My first touring experience with our new bigger caravan, we found  we were really looking for fuel before the 400ks mark, where as previously 400ks was easily achieved with our smaller caravan and we were comfortable with that. This started us looking at the possible advantage of a long range tank.

Our crew cab ute was only loaded to about 2/3 its load capacity and 60lt of extra fuel weighing 60kgs would not overload us, keeping us well in the vehicles safe loading and the extra weight was forward of the tray area towards the steering. Very good. 

We have kept a running value of money saved, buying fuel at very good prices, we think with careful buying 4 to 5  years to pay for the tank but we are planning also to keep the ute another 10 years or so. Savings are not everything, its mainly the convenience.

After some soul searching we fitted a locally made plastic long range tank, we went from a max 80lt to now 140lt, not a super big tank, best I have put in so far has been 118lts with 10 cent discount  and the cheapest for over 100ks. Sometimes we fill up just because it cheap as the last fuel up most times it been around the 80lt mark still with small savings.

Fuel gauge, we found it stays full in our Nissan Navara till we have done about 300ks and then it falls towards empty at the normal rate. The sales person explained that in most modern vehicles using there fuel tanks thats how it worked in general.

My older 1997 model ute fitted with a long range tank, the gauge moved down at a slow rate from full but was explain this is not how it works in most modern vehicles.

My decisions to go plastic as apposed to steel was the orignal tank was plastic and the long range plastic tank was much lighter then one of steel contruction and long range plastic tank was of possibly better quality then the orignal. It certainly looks better, very neat in fact. Wonder if I could talk the lady into a water tank down the other side.

Best part now, I am not looking for servos, I don't have the need to carry fuel in drums making my life easy as with spare room in the cargo area. I am to old to play around with drums of smelly, oily fuel. No one in retirement needs to do that capper.

The $1400 we spent is proving to be of good value with our touring towing our caravan weighing around 2.5 tonnes, doing side tours allowing us to buy fuel at the best price.

. Hope this is of some help.

my experience is similar to Radar above. i deliberated for years but was finally persuaded by a thread on the Expedition Portal forum. weighing up the pros and cons it concluded basically that if you could afford to fit a LRT, you wouldn't regret it. i could at the time and had a hugely expensive steel one made that took me from looking for servo's after 400km to thinking about it at 1,000km. just so worth it in convenience and buying diesel at the right price

Remember if you put a long range tank on your vehicle you will probably blow your warranty - check with Isuzu.

 What a load of you know what.  The only time that warranty claims can be refused is where the work done on your tug actually is the cause of the problem. The responsibility of any problems caused by by others is legally the responsibility of the installer.

This is turning into the usual off topic reply thread. There has not been one reply that has answered the question asked by the OP. Whether to fit an auxiliary tank or not is a personal choice. I for one am pleased I "wasted my money" and installed an auxiliary tank. Is there anyone out there who knows of the availability of after market fuel tanks (either replacement or auxiliary) tanks.

Long range tanks will usually take the original fuel gauge senders. The calibration will most likely be different in the new tank. You just have to note the new capacities in each mark on the gauge.  In my case I have an auxiliary tank above the original. When not towing I will run around 4 - 500 km before the gauge commences to drop. I just reset one of the trip odometers when I fill and use the distance on that as my guide as to fuel usage.

Hope your day improves.

Firstly I don't thing you were very fair with your statement.

I took the time to explain my feelings on this thread after noticing it had not attracted any replies after more then 24 hours hoping my experience may help.

Maybe this will be my last word on this forum. In am getting right over it. I have better things to do.

Look at the "plastic" tanks Coop.
ALL sizes and shapes to suit.
You can mix and match fuel\water, to suit.

AND. Unless a desert traveller. Who REALLY needs to be carrying 200\230 kgs of extra weight around.
The economy we get out of todays machinery it's a joke.

I'm installing a 100ltr "on floor" yellow water tank in tray. with 2 x half tanks for diesel
either side of tray behind wheel arches. 35ltr each.

100ltr water, 70 plus 70 ltr fuel.
My D-Max\van, will go anywhere.
PLUS. the 10 months I'm local they can sit in shed.

Much bigger bonus I reckon.

And that LAST line Jacko.

Says it all.

Same as running your rig on max limit weights. and everything you can get in. IN.
Regardless of whether you need it or not.
most don't.

Hi coop47, I don't know about the MUX but the Pajero Sport has the same problem the fuel tank it is way too small when towing a larger van only a 350/400km range. I decided to carry Jerry cans instead of fitting a long range tank because of 1) the cost and 2) I wanted to keep my gauge accurate 3) I wanted to retain my trip computer functions. I don't believe that they can recalibrate your trip computer or fuel gauge to give the correct information when you fit a different size tank. The only time that I used a jerry it was a real pain in the butt especially trying to decant it - not really something that I would want to be doing when I get a bit older or if I had some incapacity such as a bad back. Now I only carry one jerry as an emergency back up, it's just not worth the effort using them to try and save a few cents a litre ..that's only my opinion and as others have already said it 's your own personal preference which way you want to go.

In terms of new car warranty the dealer advised me when I asked them about fitting air bags to the Sports rear suspension that Mitsubishi will not cover any accessory that they have not approved or anything on the vehicle that is damaged by fitting that accessory - it doesn't actually void your whole new car warranty..
