Yep you are right Team Piggy the fuel transfer is taking place all the time.

Hey guys

My D4D is doing strange things at the moment since I took her down to Stockton and drove in fresh air for a while.

For the first 28k the first tank full was getting around 1060-1100Km before the green light came on.
Since this Stockton trip she is getting between 900 - 950km on the first tank but there is no major difference in fuel economy.

Must have shook her up good and proper I think.

I haven't run her down to the orange light yet and generally try to fill her up at no more than 1500km's on the odo, which has been leaving me with 35-40 litres left in the tank.

Using theScanguage I have found when the fuel light comes on there is 20 litres left.

The next question, which as a Diesel owner I do not want to experiment with, is how much of the 20 litres do we get to use before we hear a splutter?

Cheers

20 litres left is quite a few K's left in the tank. Its good to know this if ever came a time to run low. 8)

Hi Pete,

Don't know if I would want to go past 19.9 :lol: :shock:

[craig Member Find all posts View Profile Close craig]

But which tank is the 20 litres in?
Is it in 1 tank or 10 litres in each tank

[Guest Close Guest]

Its in the main tank as all the data in the above posts point to, The sub tank is constantly moved forward to the main tank by the jet pump.

I know that the jet pump is working all the time, but unless there is a small well for the suction port of the jet pump to go into you will always have fuel left in the sub tank.

So you answered your own question... ops:

[craig Member Find all posts View Profile Close craig]

How did I answer my own question?
Is there a well in the sub tank?
has anybody pull the drain plug out of the sub tank when it is empty and see how much drains out?
There is also a drain plug on the main tank, has any body been game to drain out he main tank when the low fuel light is on and see how much drains out?
It is all well and good having these fandangled gauges telling you how much you SHOULD have left, but unless you drain the tanks out no one will know :!:

craig,
(Very good suggestion.) You can answer the question for all of us by draining both of your tanks when the low fuel light comes on. I can't find a drain plug on the main tank on my vehicle, unless you have to remove the protective cover?

I agree about the comment about the fandangled gauges.

Go for it Craig,

Cheers,

I've tested my D4D and there's about 14L left when the orange light comes on. Although I was pretty confident with this figure, I still did get nervous when the light came on coming back along the nullabor trying to get to Norseman towing the caravan.

Even towing the van though, 14L is about 100km - not bad.

I'm a bit late in coming to this thread.

Whenever I get a new vehicle I always drive it until it runs out of fuel for the first three tankfulls or so and make notes on various parameters.

I have series 120 Prado with the 4.0 V6 petrol engine.

When the orange fuel warning light comes on I can drive for 90km (give or take 5km) before running out of fuel.

When using the onboard computer to show 'range', it will show 0km left at the point where I can still go for another 45km before running out.

So, on my vehicle at least, orange light means 90km (approx 13.5 litres) left and 0km range on the computer means 45km (approx 7 litres) left.

Sounds like a fun little hobby Tim...running out of fuel 3 times when getting a new car! I wouldn't recommend it if you had a D4D though!

Good to see my estimate of 14 was pretty close to the mark. I'll have to tell my wife that I was right again. She's never trusted me since I ran out returning from our honeymoon. I never lived that one down.
