fuel light flashing

fuel light flashing punto 2000

I have read a few posts about the fuel light flashing and saying zero.
most of these posts say there car didn't start, this isn't the case for me,

I have had a fuel pump problem, the car was juddering and stalling and not getting much power, the pump was also whining loudly. so I go another fuel pump, fitted the pump and the car started but the fuel light started to flash and the gauge went to empty. (which means there is a fault in the system)
I put the old pump back in to check the car since last I started it and there was no flashing fuel light with the old pump.
I do have fuel in the car for those about to say that! probably half a tank.
so all the wires, injectors and fuel lines work with the old pump, so they aren't the problem either. the problem I guess, with the old pump was the filter was most likely clogged, hence the lack of fuel and stalling/juddering.
so the new pump works and starts the car, what could the problem be?
anyone with knowledge or similar problem happen?
