I am a little puzzled, the specs say that my tank has a capacity of 89 Liters, When I reach a point where the Needle on the dash gets to empty and the Light starts to come on I go and will up.

I read somewhere that the light comes on when there is 9 liters of usable Diesel left.

However when I fill up I only get around 65 liters in the tank.

Where am I going wrong? are the pumps wrong and therfor selling me less Diesel than I am actualy getting so loosing money, I DON'T THINK SO!
Or is there an isue with my guage.

fuel gauges are exactly that, a gauge as to how much fuel you have. they are about as acurate as a blind man with a crossbow(unless he is the blind olympic crossbow champion)try running it till it runs out and see how much longer it lasts but carry a few gallon in the back

I thought running a diesel out of fuel was a no-no!

My knowledge of Discovery diesels is "0" but from past experience in other makes diesels, if he runs it out of fuel, wont he have to know how to bleed the system to get it going again? Doesn't the crap in the bottom of the tank jam up filters and injectors and stuff?

This is all very true, bleeding it shoul not be too hard, as for the crap.......mmmmm yes. What I might do is work out based on the MPG how much further I think I can go and go for that, in theory I will be ok as there is plenty of diesel left in the tank.

You Shouldn't Have To Bleed The System To Get The Engine Restarted, Modern Diesels Have A Fuel Return System That Eradicates The Need To Bleed The, Like A Self Prime, But It Will Suck The **** Out The Bottom Of The Tank. But Its Probably Best To Bleed It With The Lift Pump Anyway

Mostly! I ran out once in my old beemer and it self-primed, but too about 30 seconds of running the starter to get it going. On an old Citroen there was a bulb on the fuel line so you could prime it by hand, and my old trannie left me stranded when the fuel pump relay died and (at the time) I didn't know how to prime it myself so had to get the bloody thing recovered in the middle of nowhere in France! So I'd suggest reading the manual - it probably says in there.

Back on the thread subject, I once got several litres more fuel into my Audi than the size of the tank was supposed to be!

can a similar thing happen with petrol landys. i.e. do they need bleeding if they run low/ out of fuel?

not realy, you need to bleed the diesel as they rely on compresing the fuel to then make it explode to fire the engin. Petorol uses the spark to fire, so no fule no fire.
