I am now the proud owner of a 2002 4.0 V8 Discovery II. I am really happy with the car and have really enjoyed tinkering (I'm really not very mechanically minded so this has been mainly cosmetic touch ups etc) over the past couple of months.

The car has been converted to LPG which is fine by me as I have an AutoGas station a coupe of miles away.

My main issue with the car at the moment is that I have no idea how much fuel I have (unless I have just filled up).

It seems that when the LPG conversion was done they removed the original fuel tank and replaced it with a 30 litre tank to allow for the LPG tank to be installed underneath the car and keep the boot free.

I have no idea if the fuel gauge has ever worked but at the moment it only ever shows 9/10th full and doesn't move. My very uneducated guess is that:

A) either they replaced the fuel pump/sender when they did the conversion and this is now faulty

or

B) they didn't replace the fuel pump\sender and this is now no longer reading correctly for the different size fuel tank.

Any pointers as to how I would diagnose this would be really useful and much appreciated.

The LPG fuel gauge (4 small LEDs on the switch that changes from petrol to LPG) is less of a worry but it still be good if anyone has any experience of having as LPG car and has any pointers as to a more accurate gauge that can be installed in tandem with the fuel switch.

Apologies, I know this is my first post and there is a lot of information\waffle in there.
 
The only way you can check the sender is to remove the pump, remove the pump relay too as to not work dry, turn igntion on 2 and move the float to see if the gauge reacts to it or not

I too have an lpg conversion but on a D1. It was professionally done with a very small petrol tank.
you have no choice if the fuel gauge isn't working other than to fill it every time you can and try to keep it like that. Don't be tempted to run the LPG tank dry unless you are sure that the system can cope! Could have a very loud backfire type explosion (striking back) under the bonnet at the very least! Remember the thing the chemistry teacher did with the coffee tin with a hole at each end and gas from the gas tap? Same thing!
sierrafery's advice is sound.
Best of luck with it.
