As we have several F250's in the group I have posted photos of the long range fuel tank and pumping system that I designed and installed. So far 30,000 Kl without problems.
There is a binnacle in the cab with pump switch and contents gauge,
The floor of the load area is 16mm ply covered with marine carpet. this allows me to screw down drawer cases, boxes etc when we are on the road.
The tank has also been covered with marine carpet for appearance.

HiYa Turist, a couple of question if I may, What brand/model of solenoid valve? Where does the pump output enter the main(existing tank) ie hooked into. What brand/model of pump? Did you consider gravity fill only? What happens when the main tank is full and it starts to overflow? I am looking at something similar. It's not possible to carry too much fuel.....agreed? Thanks Nomad

G'Day Nomad.
Are you thinking to get away from the Patrol??

Anyhow.
Solenoid valve and pump were purchased over the counter from Repco. I did not keep a note of the brand.

Fuel is delivered into the main tank via the "fast fill" breather tube.
With gravity fill only you have no idea of the amount of fuel flowing and it is too slow. The pump delivers 2 litres/minute.

If the main tank overfills the fuel goes via the breather/overflow to the aux tank and will continue to "go around in a circle" until you switch off the pump.
This is why the main tank is vented via the aux tank.

The shut off solenoid is 'normally closed' and opens when you switch on the transfer pump. Same circuit.
This is to prevent uncontrolled syphoning/gravity feed from aux. tank.

Well we drove from A. Springs to Broome via Tanami without refuelling. Others were paying $3.10 lt at Rabbit Flat,

Great setup .... I have a decklid not canopy on mine and only doing a long trip every 18 months or so I'm making my tank removable. It will have a Carter pump and Cav filter attached at one end power comes from the batteries in the box beside the tank. I'm putting a racecar fill point in the top (100mm opening) in an attempt to see bad fuel. I'm using a floating pick up to draw cleaner fuel from top in case of water or particulate contamination ... instead of bottom or a small sump.
I have several disadvantages ... I have to fill mine by lifting decklid, i have to stop to fill main tank via hose over side. removing and storing etc. Better than jerrycans though ...
Once on the road for big trips I'll change to your setup .... flicking a switch while driving gotta be the way to go !!

Thanks for that Turist, gives me a lot of useful info to go on. I hope SWMBO appreciates you to the extent you are entitled to(I live in hope). Am planning at this stage to turn up at Gympie but not sure yet. We always go to Woodford at Xmas and have a great time but nearly got wiped out by a twister last time. Good thing I had a few sherberts otherwise I might have been worried!!!!!!!. Nomad

We have also got a long range tank in our F250. It is made of 2mm stainless and holds 225lts. It fits across the front of the tub just behind the cab like Turist and ours has a 3rd auxiliary battery and large tool box fitted on top of it. We have a tube going along the side of the tub to the left rear where there is a fill and vent point. To fill it is simply a case of fill main tank and then lift rear door and fill longrange tank. Fuel is transferred via up 100lt/hr pump in series with a solenoid switch and inline filter then into the side of the main tank fill tube. I have a switch with light inside cab so that it is easy to see when fuel is being transferred. As it pumps about 50lts per half hour I wait for main gauge to get down to 1/4 then pump for half an hour, and repeat this each time it gets down to 1/4. In my setup if I was to forget about it pumping it would eventually overflow out the main tank vent pipe, but with the light going it is very hard to fotget about it. It is great to be able to drive from Qld to Melbourne without refueling.
