Reply With QuoteWhy don't you pump fuel from the aux tank to keep it above quarter full while you are having this problem? Not much point having fuel in the aux and not in the main tank.

When I purchased the D4 in 2016 I had an auxiliary fuel tank fitted. It pumps fuel across to the main tank by a pump which needs to be manually switch on. When switched on the fuel is pumped into the filler tube of the main tank so theoretically is completely independent of the main tank.
We had travelled to Cape Yorke and then to Arnhem Land so we had plenty of kms up and all was working well.
Coming home 350ks north of Alice Springs the car just stopped - doing 100km/hr towing our van the motor just stopped with a message "engine fault". We could not start the the car again. The fuel tank showed 1/4 full and we had a full auxiliary tank.
Land Rover Assist were brilliant and got our D4 and camper to Sutton Landrover Motors - alice springs. Neil at Suttons is fantastic and knows landies inside out. Next day he got the car going again and said that there was no fuel in the lines so he purged the air from the lines and got the car mobilised again. Thought that I may have picked up some dirty fuel so he replaced the fuel filter.
Ran out of fuel again near the Flinders Ranges - this time i purged the fuel lines on the side of the road and got the car going again - exactly the same thing - tank gauge 1/4 full and plenty of fuel in the auxiliary.
Got it back to Adelaide and took it for warranty repairs - all they did was replaced the fuel filter again. After my protests insisting that the problem is much more than a filter I left dissatisfied. Same scenario happened again.
Took the car back for warranty and this time they said that they found a fault with the fuel sensor - after 7 days in their workshop they pulled the tank out and replaced the sensor - still not fixed. They tested the car and the fuel gauge was going up and down irregularly - they our now saying that they think it could be the auxiliary tank. They will isolate the auxiliary tank and see if there is still a problem.
Any ideas.
Thanks in advance

Subscriberi guess the question is, was the main tank actually empty or 1/4 full?
the air in the lines, is that the line between the main tank and the engine? or the line from the aux to the main tank?

With the pump type long range tanks there is the chance that the splash back can return to the spare tank on transfer.Surely you are getting an empty gauge on the main tank????

At the moment i have been keeping the tank over 1/4 full so that it doesn't happened again but for future trips I need to be able to use the last 1/4 of fuel.
Main tank still had fuel in it - no low fuel warning light.
Air was in the lines between the main tank and engine. Error diagnostics showed low fuel pressure warning.
In the main tank there are two chambers (baffles) and a small "jet" pump that pumps the fuel from one side to the other when the tank is getting low - so it could possibly be this pump that is faulty.

Subscribersounds like it has nothing to do with the aux tank.

I think so.
I doubt the long range tank has anything to do with your issue.
May have a similar issue in our Ford Territory.Last drive the 80km to empty warning came up.Drove 30km home.Next start it idled for 3 mins and stalled.Gauge reads between E and 1/4,40km to empty on the computer.20lts of fuel fixed it.

How much fuel did it have in the main tank?
How many Kms did you do before it shut down?
There are 2 fuel level sensors in the factory tank...
And your Aux can do NOTHING to impact the Primary tank.. tell Michael and his team not to mess with something that can not impact fuel flow or levels in the main tank...

Im not sure on both of your questions. The first time it occurred Sutton motors added about 20litres of fuel and unfortunately I didn't take note of how much fuel I put in when I topped the tank up.Originally Posted by Tombie
I think I had done around 600km on the main tank when it occurred. I've attached a photo of the instrument panel when I stopped the second time. Unfortunately I had already tried to restart the car again.

Supporter600 km towing a caravan at 100 kph, there won't be much fuel in the tank! Mine would be on empty with zero km to go well before that.
Even if you get 12 l/100km, which would be incredible towing a van, you would have used 72l and the tank would be reading empty with a some fuel in reserve. With more like 15 or 16 l/100km you would be completely empty. Sounds like the gauge is faulty to me. I always try to keep my main tank pretty full and regularly pump out of the aux tank.
