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 ?

Re: Need more fuel
Make sure you get a genuine one made in the Czech republic , not one of the many asian copies
