About how often should I replace the fuel filter? My car is at almost 92k and I want to make sure it stays running the way it should. Any Help?

 

When ever the fuel line is causing problems, other then that, for the Northstar motors, I beleive after the first 100K, an annual inspection is advised. I did mine prior to doing the fuel pump replacement, but doing it again to insure better performance, They aren't too costly.
