The fuel pump pressure for a 2000 Ford Expedition varies slightly depending on the engine. You'll need to consult your owner's manual or a reliable automotive repair resource like a Haynes or Chilton manual specific to your year and engine. These manuals will give you the exact specifications.
However, a general range for Ford vehicles of that era is 35-45 PSI. This is not definitive for your specific Expedition, so do not rely on this number for diagnostic or repair purposes. Always consult your owner's manual or a reliable repair source for the correct specification.
