Along the inside of the frame rail near the driver's side rear door as I recall, and you'll need end wrenches to gradually unscrew the nuts to allow the fuel to drain out. Wear safety glasses and rubber gloves and have a fire extinquisher nearby. Chock the truck wheels to keep it from rolling while your under the vehicle. You shouldn't need to raise the vehicle. If you do, you'll need safety jack stands on a hard level surface.
Look up your make year model on http://www.autozone.comHow do I change the fuel filter on a 2000 Chevy Silverado?I'm not looking at the specs for the truck in front of me, but most EFI vehicles use electric fuel pumps that pressurize the fuel system.
Before you do anything, disconnect the negative battery lead, no smoking or open flames, then depressurize the fuel system. You can do this several ways. Normally loosening a fuel line after the gas cap is removed, will release the pressure. Just be prepared to have gas or diesel spewing out. I'd recommend eye protection and gloves, plus have the fire bottle handy....just in case.
Don't do like my Redneck friends and try to work on the truck after a six pack while smoking a Marlboro.....
Most fuel filters are located in the fuel line itself. Many on newer vehicles are under the chassis directly under the driver's seat. Have your eye protection on, a catch container for remaining fuel under pressure or draining from the lines when you loosen the fuel filter for removal. DO NOT GET IN A HURRY WITH YOUR WRENCH! By that I mean be gentle, slow turns, no sparks.....otherwise St. Peter will still be laughing when you get blown into the gates of heaven....Angels will be rating your performance with those Olympic card things 1-10.
It's a simple repair, and the fuel filter is normally less than $15. Just keep in mind common sense. Gasoline per gallon has the same explosive potential as 11 sticks of TNT. Vapors Explode, gas on the skin or eyes causes 2nd degree burns, fumes get you high and cause brain damage.
So do this outdoors, and keep in mind a mistake could be serious burns or fatal.
