The 255L/hr pumps can provide more fuel flow and volume over stock. Keep in mind this does not mean anything if the car's fuel injector pulse timing isn't changed or the fuel pressure isn't changed. Otherwise the 255 pumps are a good quality replacement unit which tends to be a little better quality over some of the more common parts store units. Given the price difference between an OEM equivalent and a 255L/hr unit there isn't much reason to not get the 255 since it will act like a stock unit and provide room for growth if desired, not too mention the idea that you do not want a flaky or weak pump to cause the engine to go lean.
One test, before replacing the pump, I would try would be to clamp off the return line to verify whether the fuel pressure regulator is working as it could be letting the fuel return to the tank and not allowing pressure to build up.

What is the benefit of a Walbro high pressure fuel pump compared to lets say a stock one?
