* On the frame rail: This is the most common location. Look along the frame rail, somewhere near the fuel tank, often near the back of the vehicle. It might be tucked up fairly high and difficult to see without getting underneath the van.
* Near the fuel pump (in the tank): Some models have an in-tank fuel filter, meaning it's integrated into the fuel pump assembly inside the fuel tank. This requires dropping the fuel tank to access and replace.
To find it definitively:
1. Consult your owner's manual: This is the best resource. It will have diagrams and specifications for your exact year and model.
2. Check online repair manuals: Sites like Chilton or Haynes offer repair manuals specific to your vehicle's year and engine. These often have detailed diagrams showing the fuel filter location.
3. Use a parts diagram: Enter your vehicle's year, make, model, and engine into a parts website (like AutoZone, Advance Auto Parts, or Napa Auto Parts). Their parts diagrams often show the location of components.
Without knowing the exact year of your Chevy G20, providing a more precise location is impossible. Remember safety first – disconnect the negative battery terminal before working near fuel lines.
