The fuel filter is located on the inside of the drivers side frame rail under the cab. You will need some end wrenches to change the filter out. Be careful when breaking the fittings because there will be pressure bleeding off.

Safety recomendation: Disconnect battery before proceeding.

On all C/K's of this body-type 88-98, the fuel filter is located under the driver's side door inside the frame rail near the crossmember that supports the tail of the transmission. Replace it with AC Delco part GF-626, FRAM part G3727, or other comparable brand corresponding metal bodied filter. You should use a flare-nut wrench for the line fitting and one for the filter fitting. I'm not sure of the size needed for the filter, but the line should be 5/8".

For SFI engines ('96 and later) you need to bleed off the pressure in the line. Locate the pressure test port on the fuel rail under the hood, remove the cap, press valve to relieve line pressure and recap valve. If ground clearance is not high enough to get under vehicle and work, raise it with jack and rest frame on jackstands.

* Caution: Fuel in lines and filter will run out once fittings are undone. Use fuel safe container to catch fuel spill.

Take wrenches and hold filter from rotating, while loosening line fittings. Remove Filter from bracket by sliding and manipulating fuel lines for clearance, and slide filter out of bracket.

Reassembly is reverse of disassembly. Tighten fittings snugly. Reconnect battery, turn ignition on (do not start). Pump will make brief whirring sound - less than 5 seconds. Check for leaks. No leaks - good. Now you can drive again.

Hope that helps.

GM. relocated the fuel filter in 2004, and put it inside of the gas tank.

Only if you think you have a bad fuel filter, when GM. put the filter in the tank it don't seam like there is much of a problem with the filters.
