I replaced my fuel pump @ 250,000 just for the sake of it. It was
working fine. I'm told its a High Volume Pump so its gonna make some
noise. I do notice a difference with the new pump when I go around the
S Curve's and on some on & off ramps, with the old pump there was some
hesitation from the fuel pump , but with the new one I can hold at a
steady speed then accelerate and won't hesitate.
Expect to maybe replace other componnents such as the sending unit,
intank filter reffered to as a Sock, Return Line, High Pressure Line,
Tanks Straps, 2 J Nuts and 2 Bolts. It just depends how badly rusted
these parts are. SOme times they just disitergrate when you try to take
Fuel Pump replacement for my car was $555.00 for all the parts listed
above except the J nuts, straps & bolts.
The Fuel injectors are still the originals.
