• Necessary tools
It is always a good idea when making any repairs on a car to have the tools that you need to hand. The tools and equipment that you will need to replace the fuel pump on a 2001 Chevy Impala are: A replacement fuel pump, a socket wrench, a half inch wrench, rubber gloves, some rags and a fire extinguisher just to be on the safe side.

• Replacing the fuel pump
Make sure that the engine is cool so that you do not burn yourself, and that the engine is off. Put on the rubber gloves to protect your hands: The dirt on an engine can be an irritant.

Once you have opened the hood, remove the cover from the battery. Have a look for the negative terminal on the battery (it will be indicated with a minus sign) and using the half inch wrench, unscrew the nut and remove the battery cable.

Find the top fuse block, which is on the passenger's side of the engine compartment and remove the fuel pump fuse. This is the one on the top left and is horizontal.

You then need to open the fuel compartment that is on the driver's side near the back, and make sure that you unscrew the fuel cap so there is no pressure in the tank.

Open the trunk and unscrew the fuel sender panel with the socket wrench; you will find it on the floor of the trunk. You can then unplug the electrical connectors on the fuel pump, and then loosen the clamp that is on the fuel line and that connects to the pump. When you disconnect the fuel line, some fuel may spill so be careful.

Remove the fuel pump, and replace with the new one. Re-connect the fuel line and make sure the line's clamp is secure. Plug the pump's electrical connectors, replace the panel and fuel cap and put the battery back together.
