Auxiliary fuel tank

[dalil]

Hi is it possible and legal to install fuel tank instead third raw seats.
50 litres would do.

[~Rich~]

Well you could probably get something made up but I'm pretty sure it would end up expensive unless you could make it yourself.
Or do what Gordon has done:

Not sure about legalities, are you talking permanent or temporary?

Firstly Dalil,
I just need to hijack your thread for a second, sorry

Hi Rich,
I have been through the thread you posted and checked out a few of the options, when I have done store checks they all mention auxiliary tanks for diesel, I am wanting to use one for petrol, is this something can just do or is there some legalities around only using the auxiliary tank for diesel?

Also I was under the impression that if the auxiliary was gravitated into the main tank rather than pumped in this screwed up the l/100 calc. I know this isn't particularly accurate by all accounts however this does give you an idea of how you are actually going. I'm not sure but maybe you can go into the vehicles computer system somewhere and change the fuel tank size to whatever the auxiliary and the main add up to.

I'm not sure how they measure the fuel flowrate for the calculation, but the auxiliary tank on mine gravity feeds into the main tank, and the instantaneous l/100 readout still seems to work quite normally. The "distance to empty" indication on the other hand, is meaningless until the auxiliary tank is empty and the fuel gauge is reading the contents of the original tank only.

(At least in WA), you can't have internal petrol tanks.

Cheers,

Gordon

Does anyone know where you can buy the rooftop tank Fred Nerk has in that thread? He said OL but there's nothing on their (crappy) website.

[dalil]

Thanks guys, I know place who makes tanks for hydraulics maybe they can help. I just dont like spare wheel on back as i had it on landcruiser.

This might help

Hi Ben_Vapid.

The rooftop tank I have is the same as the two that Gordon (gghaggis) has used in the rear of his RRS
Mine was bought from Opposite Lock (North East Road Windsor Gardens near Adelaide). They had them on display and in stock. There are other shapes and sizes to choose from.

The OL web site used to show them but the new/updated site does not. The site does not look finished.

Where to buy?
Poly Fuel Tank 55Lt Univ Fit - Dolium Pty Ltd (http://www.dolium.com.au/view?command=cman_view_webpage&webpage_id=120&pkey=dolium&inp_item_id=FTU55P)

or

BOAB Solutions — 55lt Universal Fuel Tank (http://www.boabsolutions.com.au/collections/fuel-tanks/products/55lt-universal-fuel-tank)

They are not recommended for use with Petrol when the tank is in direct sunlight though.
Neither are they recommended for use on roof racks.

[Ben_Vapid]

Thanks Fred and Rich.

I only want something for trips that I can then remove, and it would need to go on the roof. I might also look at a dual jerry holder for the roof.

[~Rich~]

I carried 3 x 20 ltr Jerry cans on my rack for the geographical centre of the Simpson.
If you take a second spare as a carcase up on the roof as well 2 of the Jerry cans fit inside the spare helping keeping them upright.

Slight hijack .... Rich, I notice a LR tank in your signature. So did you need that and 3 x jerry for the Simpson trip?

Regards,
Scott

[~Rich~]

Yep, needed it just in case!

Mind you the idea is that you empty what you have up top asap to reduce the weight up high.

[Fred Nerk]

Rich is quite correct. It is not recommended to use the tank on roofracks. The the support provided by a roof platform would be similar to a ute tray and I am comfortable with the system. I put a rubber mat (off-cut from boot liner) under the tank to reduce chaffing.

We crossed the Simpson the long way (ie with four north south crossings) with at least 25 litres to spare.

Anyone considered those plastic internal square tanks that sit along the footwell behind the front seats? Evidently they take 80 to 100 odd litres. And you remove them after the trip.

Their downside is that they do not connect to the tank ... which maybe a strength too ...

I am not sure about how to get the fuel up to the main tank without using a carrying can setup ...

Depends on what fittings are on the tank. I have used something similar before that had an outlet at the bottom tank and an inlet pipe at the top of the tank.

Simply make up a fitting which allows you to hook your compressor up to the inlet at the top of the tank, and pressurize the tank. You will then be able to transfer fuel from the outlet up into your normal vehicle fuel fill point.

I had valves on both fittings - one to control the fuel flow, and the one on the inlet to allow me to release the pressure in the tank after I had transferred fuel and disconnected the compressor.
