Where is the fuel filter located on a 2004 Chevy Silverado?

Answer 1

The fuel filter is located in the back left, top, of the engine. It is just in front of the second battery( if you have one). I have replaced it several times. Once you have managed to loosen it, you have to pull it out through the wheel well. It costs about $50.

Diesel or gas? Diesel is under the hood, passenger side, in front of the firewall, near where the second battery is. Gas is in the tank. Its supposed to be a lifelong filter, but I've had to replace them. Your best solution is DON'T drop the tank! Get a couple of hands to help lift the BED of the truck off the frame. Disconnect; the taillights, the fuel tank filler spout, (there's a ground wire next to it also) and 8 bolts to the bed. Slide the bed back or off completely, if you have room. Be sure to scrape loose and brush off all the dirt you can before pulling the pump housing out of the tank. Trust me, I've done it both ways and this beats draining the gas, dragging it out, pushing it back in place.

Starting in 2004 G.M. moved the fuel filter into the fuel tank.....as part of the fuel pump Assembly.G.M said that it is non-serviceable.

I spent about an hour. A tech at the dealership also told me it is part of the fuel pump assembly, which is STUPID, because now when it get dirty, I have to replace a $400 fuel pump instead of a $12 filter.
