Hi Rodger22,
Thank you for the donation.
Seems fuel pumps for this model don't last very long.
FPR is intank with the fuel pump. With an external pump, the intank FPR is before the pump so fuel rail pressure is not regulated and can result in engine rpm fluctuation.
Were the 4 pumps you mentioned all external or was it the intank pump?
