Where is the fuel pump in a mazda 323 1997 1.8 executive thanks also when the pump is replaced will i need to replace any other components, also will i need and special tools or equipment. many thanks.

The fuel pump is in the tank. I think you can access it by remove the rear seat bottom cushion. You do this by pushing in at the bottom to push it back toward the rear. One hook on each side. This should expose a round access cover. Remove it and the pump and fuel sender assembly are there. You usually have to rotate the ring counter clockwise about a quarter turn. Usually a hammer and chisel is needed to break it loose. Install a new ring with the new pump.

If no access, drop the tank.
