Fuel Filter!!
How often should you change the fuel filter?
Bought the car with 78000 on it and just hitting all the basics, changing fluids out and plugs and wires....
I found a brand new a/c delco fuel filter off ebay for $28 bucks so I went ahead and got it, but just want to know if it is necessary to change it out or not.

Here is the tech article on how to change your fuel filter. You should change it once a year if you drive it everyday.

On the '00, the fuel filter is located on the frame rail on the driver's side, close to the tranny/differential area. I went to the dealer yesterday for some work on my wife's DD and asked about the cost of a fuel filter from them - $68.

There are three different fuel filters on C5's. The early years with the return fuel line used a cheap ~$16 filter located on the frame rail. Mid-year C5's had a fuel pressure regulator incorperated with the filter, cost around $45. Late year C5's (and C6 by the way) have the fuel filter in the gas tank (around $300 to change).
The good news is that the Shop Manual says you never have to replace the fuel filter unless it is a problem (clogged).
