Does anyone who has a RR or Disco have this happen:

My question is should there be such a large change to the indicated level when petrol is on/off?

Is this a sign of a dodgy fuel pump? or is this normal??

TIA

Sounds to me more like a dodgy earth on the gauge!

No fuel guage is any where near accurate unless you work out on the same level surface what each incriment means as they are operated by a float in the tank, nothing to do with the fuel pump.

As JD said it could possibly be something like a loose earth but I wouldnt be all that fussed about it.
