Thread: 2014 Discovery

Hi,
I looked up the Opposite lock aux tank - see below.

In the others they have a twin filling system, so you fill one tank then you fill the other. With the OL one it appears there is a Y connection inline going to both tanks.
My thoughts
Advantages
You may be able to keep the feature to stop petrol being loaded
You do not have to move the nozzle

Disadvantages
80 litres - 20 litres less than others
Not sure if I prefer filling the tanks at the same time.
They may have issues with hi flow

I reckon if you get into the habit of filling the aux tank first you have a good chance of realising you are putting in petrol before filling the main tank. Sounds silly I know.


OL AIX tank details
Fuel tank to suit LAndrover Discovery 3&4

S/Steel Aux Fuel Tank 80Lt (replaces Spare wheel)

Made from 3CR12 stainless steel for excellent corrosion resistance.

Uses the space where the spare wheel was located. Fills via a Y filler located in the main tank filler line so that both tanks fill together.

A transfer pump is included in the kit and would be wired to a switch inside the vehicle to allow fuel transfer whilst travelling.

The tank is very strong and allows sufficient space around it for normal servicing etc. An optional HD steel guard is also available for the more serious off roaders.

Please note that when filling this style of tank at a fast flow pump there may be issues blowback. It is always recomended to use standard pumps for filling.

I guess it's changed since mine being installed in Nov 11.

No transfer pump. OL tanks fills first....I can actually put 90 litres in, then stop, with original tank showing less than half as the fuel transfers to it, and then as you drive the original tank gauge will slowly increase to full. It has a non return valve between the two tanks.

Tank capacity is 95 litre.....the biggest fill I have done was 175 litres....which I guess original tank was extremely close to empty.

What you have quoted appears to be the Dolium tank which I did not go with as I needed to carry more fuel....Dolium tank has the optional bash plate. Maybe OL don't sell my tank anymore ?

Not a fan of long ranger due to the fuel pickup line corroding causing pump failure....a known fault, as advised by long ranger. Also on the CSR I had to gain access to the long ranger as the float extension provided broke, showed no fuel, so no fuel would transfer.

Liked the brown Davis tank for capacity, but a friend that sells them, told me they have had a significant number of returns due to welding failures.

Brett.....

I'd agree with Brett's comments.

When I had mine fitted, they told me it was 80 litres. But I've regularly been able to get a lot more in than that. I always thought close to 100 litres - 95 litres sounds about right.

I have no trouble filling mine - hi flow still works OK but you have to be careful about the angle you hold the filler nozzle or it can "spit" back at you a bit.

With mine, the aux tank also fills first.

I have the Outback Accessories AUX tank from Opposite lock, similar to the Stainless one but has 90ltrs, it drains into the main(gravity feed), so you fill your tank as normal, no Y, works really well.

Baz.

On the Opposite Lock web page they mention a transfer pump as included in a post above.

I guess there are different models around with different approaches.

Missed that - doh!

Here's my take...
If you are that Inattentive that you can't remember what fuel to load then don't be driving, as you present a hazard to yourself and others

Stainless is a waste, diesel covered metal won't rust

90l isn't enough it's never enough...

Goes close though

On recent trip to Tassie, I topped up at Norseman and assumed that I would get through to Ceduna without stopping for fuel (used to be able to make Ceduna comfortably in Prado with 180 litre tanks).

The Disco made it from Norseman to Port Augusta without problem - still had plenty left in the main tank (admittedly we had a tail wind most of the way across).

On the way back, we camped at Coffin Bay for a few days. Fuelled up at Ceduna, and that got us right through to Kalgoorlie, with still more than half the main tank showing on the gauge when we got home.
