Tanami Pump

when we last went up to cross the simpson one guy had 2 small kegs mounted under his tray with a valve and copper nozzle from in the keg at the bottom and tubeless valve stem at the top.same principle but he had water in them.pumped them up and you could get mostof the water out with one inflation.good idea mees thinks!Paul

Hi Willem.
Your Tanami pump sounds like a real labour saver, but you should be very carful with it. You don't say if your made up outlet system is locked down solid and air tight. If it is it could be a ticking bomb. Don't have a jerry at home with me at the moment so going by memory on sizes, all 6 sides could add up to something like 790sq inches. Now multiply that by say 20 PSI (nothing for an air pump) and you have a total internal load on the square cornered jerry can of 15.800 lbs. Don't get me wrong the pressure system is great and I use it lot in my boat and 4x4. The safest way is to use the system you have got but have no valve core in the stem and use one of those tapered plastic nozzels that come with most air pumps for air beds etc. That way you have to hold the nozzel it in place by hand which isn't very air tight and can release the pressure at will to keep it at about 2-3PSI which is heaps.

I have a real Tanami Pump and it has a pressure relief valve so that the internal pressure within the JerryCan does not go above 5 or 10PSI. They are great and have used it on many trips and do not have to move or lift the Jerry Cans.

I believe you are OK with your invention Willem.

Mine also has the pressure relief valve but I reakon this is more to protect against "commercial litigation".

As Roachie says, air goes in, fuel (or air) comes out, so there should be no real safety issue with your invention.

The one plus with the pressure relieve valve is enabling a quick interuption to flow by the instant release of the built up (low) pressure. Fuel flow stops immediately.

Now all you need to complete your invention Willem is an adapter air hose.
I made up one that has a clamp style air connector at both ends and a valve towards one end. I connect one end to the spare tyre and the other to the Tanami Pump. Crack open the air valve (tap) to start the flow. No need to get the pump out as there is enough pressure in the tyre to empty three jerrycans (60 litres) or more.
I usually inflate the spare to 55 psi for this purpose and it is easy to reinflate the spare "at camp".

Just remember, it pays to ensure the jerry is earthed to the vehicle, or ground, to eliminate static electricity.

This fantastic device really does made the transfer process effortless and "enjoyable"

Good luck with your invention Willem.

Willem We have been using the air system for years and if you were to have a decent look at what has been suggested you might change your mind , all you need is some sort of air system ie hand pump would do . We used to fuel the tractors up on the farm with the same system out of 44 gallon drums ,pretty quick to . Cheers Roughneck
