Where is the fuel filter located and how do you replace it on a 2000 GMC Sierra?

Answer 1

I have a '96 Sierra 1500 Z71 Ext Cab and the fuel filter on my truck is located on the backside of the rocker panel (its attached to the body of truck) of the extended cab area. If I remember right, you will need a 16mm wrench & a 20mm wrench. Once you disconnect the fuel lines a small amount of fuel will drain, so make sure your not directly underneath the filter but over to the side. Then to get the filter out of the holding bracket just slide it out. It will only come out one way and if I remember right it slides towards the front of the truck. When replacing the new filter pay attention to the flow direction arrow on the filter. Hope this helps!! What you need to do is find the fuel line. On most vehicles, the filter is closer to the fuel tank. It should be about 3 to 6 inches in length. To remove, you either need a set of line wrenches or a fuel line clip remover/ expander to remove the old filter. I have a 94 Sierra and my filter was located right below the cab corner ( mine is a standard cab) and it required line wrenches to remove. I'm not sure which tool you will need for your's but if you can find the filter you can look to determine. Hope this Helps you out! I did this last weekend. It is located on the frame about 1 foot from the gas tank on my extended cab short bed. I just used a crecent wrench and was able to remove is fairly easily. Watch out for gas draining from the lines. ANSWERThe filter is inside the left frame rail just in front of the gas tank. You need to remove the gas cap and bleed the fuel pressure before opening the system. There is a schrader valve on the fuel rail you can use to bleed any pressure. The easiest thing is to have the guys at the oil change place swap it out for you next time you have it in for an oil change.
