Need more fuel

Hi!
I have figured out that my walbro 255 inline fuelpump not deliver enough fuel for my engine,it sucks at 4500rpm and the wbo2 leans out,new filter installed.
I have run whith a fuelpressure gauge thats 43 psi under low and medium trottle but drops to 10-20 psi at full trottle and the engine just dies more or less.

So what do you recomend,install a new external pump or a hotwire kit ?

Given your location , maybe the popular Bosch # 0580254044 "044" pump used in many European cars might be a option and a hot wire kit to ensure good Volts at the pump.
Make sure you get a genuine one made in the Czech republic , not one of the many asian copies
