Review on High-Performance Delphi FG0089 Fuel Pump Module for Enhanced Efficiency and Durability by Adam Cooper

Couldn't figure out why my 99 speedometer would oscillate frequently, typically under hard acceleration for years after changing everything from spark plugs, wires, cap mass sensor, throttle position sensor check, EGR etc. The last resort was the fuel pump, although it worked and started for many years, it was sluggish on the gas. Well it works fine and takes 0ff like it should. I wish I had changed the fuel pump a few years ago, hopefully this will last a while.
