g'day.

could anybody help me?

My fuel pump is broken.

Could anybody explain were to locate and how to change a fuel pump in my 1996 second generation Mitsubishi Magna?

Well on the Te`s and up i know its under the rear seat. So might be the same for your car, remove the back seat, there may be a cover on the floor to remove and you should be able to get to it from there.
