How do you change the fuel filter on a 1997 GMC Suburban turbo diesel?

Answer 1

First you need to remove the fuel cap, to release the suction from the tank; then you remove the manifold cover, using a 10 mm socket with an extension. Behind the manifold is where the fuel filter is located. Unscrew the black ring that tightens down the fuel filter. Once the ring is removed, grab the paper ring where it says "Pull Here" and begin jiggalling and pulling until the filter comes out. Once you pull the old filter out, replace it with the new on. Be careful to properly align and press the new filter in its place. Now replace the black ring and tighten down. Next, get a 5/16 clear hose and insert it on the black bleeder valve that is on top of the filter you just installed. Place a container at the other end of the clear hose line. Turn the black bleeder valve counter clock wise. Without starting the engine, carefully turn the key ignition on. You'll might be able to hear the fuel pump working. At that moment you will see fuel passing through the clear line. Once you see no bubbles in the line, turn key to the off position. Tighten back up the bleeder valve. Then start you engine. If the engine doesn't start then you may have not gotten all the air out of the system, and now you'll need to take it to your mechanic or dealer. That is it.
