Where is the fuel pump located on a 1997 ford powerstroke engine?

There can be an electric fuel pump located on the frame rail under the driver seat area but there is also a mechanical pump that is located on top of the engine near the turbo. The powerstroke uses an injection pump (sometimes called a fuel pump incorrectly). The injection pump on the 1997 is below the lid you must open in order to change the diesel fuel filter. If it needs to be rebuilt you are looking at approximately one thousand dollars so shop around it may make more sense to purchase a new one rather than rebuild.
