Dealers does not sell fuel pump on it's own only whole fuel delivery unit which is around £800. You can get VDO pump on it's own which is the same like original pump for around £120

If the problem only persists on half empty tank and it runs fine with full tank there is a possibility that some work has been done on fuel pump, possibly changed pump and it was not correctly seated in tank. Very easy to put it in incorrectly if you do not know what you are doing. Have seen it fitted incorrectly on several occasions.
