For anyone buying a replacement pump, I would recomend a pattern unit from Brit-car.
The original unit is known to be a problem on Land Rovers( why oh why not fit a unit from a cheaper car) and all you need to do is remove the sender unit and cut out a small plastic lug.
Cost £185 ex vat.
This unit has worked a treat and was reomended to me by a Morgwn specialist and LR enthusiast.
