CDTI Auto More fuel woes

Hi, Having a fuel problem with my 2003 CDTI Auto.

About two months ago the car refused to start, i suspected the Under bonnet fuel pump, so i tapped it with a screwderiver, and bingo! the car started, it was like this for a couple of weeks, sometimes it would start, sometimes not, but a little tap on the pump always got it going. So i changed the Pump for a mid priced one and all was good again.

Got up yesterday morning, the car started fine, a quarter of a tank of fuel, drove half a mile to the petrol station, filled up with Diesel, car then refused to start at the pump, called RAC. He plugged in the diagnostic, at first he said it had a high pressure fautl then changed his mind and said a low pressure fault.

He then checked fuses and power to under bonnet pump which were all ok, he said the under bonnet pump was hot!

So...a tow in to my local garage, they fit a new, but cheep and very noisey under bonnet pump.

They phone me to collect the car, the car now starts fine, but drives abismal, no power, and it wont rev above about 2300 RPM.

They are a little stumped, i did mention to them the other, in tank pump.

With the fuel filler cap off, i think it can just be heard but its very quiet. The in tank pump was changed around 4 years ago.

I would be very gratefull for any pointers.

Thanks.
