How to hold down that 100kgs of fuel would also worry me!

That was my thought. There used to much, much bigger versions of these in use with the helicopters when I was in the Army thirty years ago. It's an interesting idea, but rollover issues might be a bit worrying for any fuel inside. I just wondered if anyone had used or seen them used in vehicle?

Flexitank make excellent products for marine, off road and on road systems and it remains on our list. We have been using their footwell water tanks for around 15 years along with hundreds of other 4WD owners with no problems. Restraining 100kg is something a seatbelt does simply and easily and can be done with a decent ratchet strap with no issues. We use them to restrain 60kg of fuel on the roof all the time and have done over 20 Simpson crossings using that concept so I personally have a great deal of experience with it and am very happy with the flexibility it offers. I see accredited fire units, a ute with 200l of water and a pump all held down with a couple of straps and that concerns me a touch.

Carrying diesel fuel internally with proper seals and containers is not an issue the only time it becomes a problem is if you spill it and the flexi tank has a great catch system around the filler and we use Mr Funnel as part of the tank fill process so never had a problem

We are taking a different approach. We will be fitting a Dolium tank to a custom build sliding platform in the rear only when we need the range. Combined with three JC on the roof that will give me around 190l and I can get almost anywhere with that whilst towing our Ultimate so no problems for us.

For fuel transfer we use a special 12v transfer pump with filters and everytime we refill in the outback we use a Mr Funnel aviation grade funnel as one more safety device and that has worked extremely well for the last five years

Hi Rob, thank you. Could you elaborate on the details of the fuel transfer pump at all please?

Cheers

For those towing camper trailers,look into a generic plastic tank fitted to the camper trailer,plausible due to weight restrictions.A caravan would be over the weight ratings.

Shane thanks there is actually plenty of choice but the one we use is from Alemlube and is a 5200 diesel pump transfer kit. We don't like toy parts due to poor design and lack of reliability. This is Italian made by Puisi in Italy and a well sorted kit. Around 50l per minute so ruddy quick and at times we think perhaps too quick but you deal with that when you are transferring fuel. A slow trigger finger is all you need. Not exactly the cheapest thing around and you can get lots of lower cost versions which most likely work well and from places like Repco and similar automotive outlets but this is the one we settled on. As well the Puisi is fully repairable which is something else we like. The design of our internal sliding storage system will be taking all this into account. We have purchased all the gear to go onto the ground floor of the slide first. From there we custom build the slide and first floor storage system. This is not a process you take on lightly as it aint that cheap but it is considerably less expensive than a underbody tank and the rear bar spare wheel carrier and offers us a lot more flexibility and less weight to carry. All of which are key aspects of what we personally want from this project

Thank you very much Rob!

Anyone have the fitting instructions for the LRA tank?
