Can someone tell me where the fuel filter and fuel pump are located? I want to be proactive and replace the fuel filter, but would like to know it's location and how easy it is to get to. I have changed them out on many other vehicles before. I can look for it, but thought someone might be able to save me the time of hunting for it. Also, where is the fuel pump? Is it inside the gas tank like it was with my Tahoe? If so, does it cost $600 to replace like it did in my tahoe? Thanks for any input you can provide.
