Thread: Long range fuel tank Disco 4

Hi guys,
I spent quite some time over Easter fitting a Brown Davis 120 ltr Auxillary tank to my D3.
The instructions left quite a lot to be desired!
An example is an angled bracket that fits to the removed heat shield fixing holes, it has a short and long side with the holes in the same position on both sides. The trouble was that no where in the instructions does it tell you which side fits to the chassis or tank!
I had to jack the tank into position a few times to figure out both the above bracket but also the best direction for the outlet hoses to face.
Also the supplied hose fittings for the filler just did not work. I ended up having to purchase a 135 degree radiator hose ( which is not correct for diesel fuel) to temporarily connect the filler as on Easter I could not source an appropiate part. I ended up fitting today a 38mm 135 degree pipe with straight approved hoses.


Work in Progress.


Hose maze. Note the hose right in the centre of the photo at the top.
It may be the exhaust from the Air Compressor?
On the left at the top where the filler neck goes through the body you can see the end of what I presume is the rear diff breather pipe.


More hose maze!

I chose the Brown Davis tank for it's larger capacity.
I'm happy now it's in!

The exhaust for the suspension system is a 19mm hose that is shown in the WSM as venting to atmosphere inside the top of the compressor box. Perhaps yours has been re-routed.

It was attached to the original filler pipe along with the other smaller breather pipe, you would think that both of these should have some sort of filter attached to them!
The thick one has a sort of slotted vent fitting at the end but no filter.

The compressor exhaust pipe already has a filter but not at the end.

There is the fuel tank vent pipe and the rear diff breather pipe. The fuel tank vent pipe is meant to have an insect trap in the end. Around here any open pipe is soon used by mud wasps! Actually, I've had to remove mud wasp nests from the rear window glass.

The main tank and the auxillary tank vent pipe both attach to the filler neck.

If the small one is the rear diff breather I'm definitely fitting a filter to it!

The vent pipe or the breather pipe? The breather pipe connects to the top of the filler neck and gets blocked at the tank by fuel when the tank is full to cause back-pressure to cut off the nozzle. The vent pipe vents to atmoshpere near the top of the filler neck and connects to the rollover cut-off valves at the tank. It allows air to be drawn in as the tank empties. A filter seems appropriate.

Hi Rich.

Is the Brown Davis tank a pump up or gravity feed? They appear to be a very well priced tank for their size.

Thanks

It's a pump, you can see the pump against the wheel arch fitted vertically. It pumps up to the brass fitting you can see near the top of the main tank filler.
I got the tank for just over $1300 as I had it delivered to my mechanic. Discounted 10% plus $80 shipping.
