When it gets to zero, it isn’t actually zero. I’ve gone 30 miles beyond zero before, and still only put in 98 litres. Although I thought the tank was 98.5 litres but maybe there was a change for 2011 |

Hi, not sure that this will answer your question fully other than it may be that there’s a bigger “reserve” than one might think;

The tank should never be run dry and the reserve is there to save the fuel system sucking up air or sediment. If it's a 4.4 the DPF regeneration doesn't work with less than 1/4 tank so it's never a good idea to run theses cars with less than that in the tank. 2012 TDV8 Vogue (L322) |

If that's your only problem on a 14 year old Range Rover then you are a very fortunate chap |

After 12 years theres going to be all sorts of crap in the bottom of the tank, I rarely go less than 1/4 tank except on a long run, I think most I've ever put in in one go was about 95l on a trip to Thurso.

The input to the fuel pump sits on the bottom of the tank, so will pick up regular fuel sediment / water present in the tank whether you run it low or not. Fuel sediment is also stirred up all the time due to the vehicle's movement, so will be sucked up constantly and filtered by the fuel filter in the engine compartment.

That makes sense now I think about it. My guage over reads the how much is in there and I have on occasion been able to get over 90 L in there. I think on earlier cars there is an option in the GAP IID tool to recalibrate the fuel guage but unless it's in teh full and untested list I haven't found it and if it is I don't want to mess it up by trying. 2012 TDV8 Vogue (L322) |

I'm never sure why people think there will be sediment in a fuel tank. The simple act of driving sloshes fuel all over the tank internally, so you're always sucking up thoroughly mixed fuel and any small particles get mixed up with it and then filtered out in the fuel filter. Drives:

Maybe just a useful scare story to stop people running their tanks too low and causing damage by not so scary sounding means - air in the fuel doesn't as bad as sand in the fuel. 2012 TDV8 Vogue (L322) |
