2003 Fuel filter
I cannot locate the fuel filter for changing, it says it is in the rear of the car on driver side, anyone have a picture, video or help locating on my car I would appreciate it.

You may have the newer FFS fuel system starting with VIN 35114929 in 2003...fuel filter is not on the L/H frame rail where it would normally be on pre FFS systems !!...fuel filter/ pressure regular is in the tank !!

And if you do have the filter in the tank (as my 04 does) and it does need changing because of fuel flow issues, get ready to spend (unless you do yourself) hundreds maybe a thousand to drop the tanks and change the filter. Just another, IMHO, dysfunctional C5 design flaw by Chev 'smart' guys.
I hope to avoid gas and filter/sender issues by only using top brand gasoline (my preference, Shell), never let the fuel get much below 1/2, and add a bottle of Techron at every other fill up. After 6 years of ownership, so far no problems.
