To be certain, it's best to:
* Consult your owner's manual: This is the most reliable source of information specific to your van.
* Use a repair manual: A Haynes or Chilton repair manual for your specific year and model will have diagrams showing the fuel filter location.
* Search online: Search for "[Your Engine Size] 2000 Chevy Express fuel filter location" on YouTube or a car forum. You might find videos or pictures showing the location.
Be aware that working with the fuel system involves flammable liquid and requires caution. If you're not comfortable working on your own vehicle, it's best to have a qualified mechanic perform the fuel filter replacement.
