I was busy working on another car and i had
a friend swap out the stock pump for a 255.
He reads the directions and reinstalls the pulsator
on top the pump . I went to the track and now
I am experiencing a lean surge , like its running
out of fuel . car was down 3-4 mph on a night with
much better air . still ran 12.91 on plain tires but
i was hoping for some 12.70's .
any body have problems running the factory pulsator ?

i never reinstal the pulsator and have yet to have a problem.
i would remove it and put a piece of FI fuel line in its place.
did you get the hot wire kit?wise investment

 

If I would have done it myself I
would not have used it . But my
main question I guess is can it limit
the flow of fuel of that pump to the
point of starving for fuel on a 325 rwhp
car ??

 

honestly, i believe it can and has done such on your car.
have you checked your voltage to your pump under WOT i am sure you will see a decrease in voltage,its small but it is enough
