This document is an exploded parts diagram of the fuel system for a 1997 Ford 7.3L (Power Stroke diesel) engine, titled "'97 7.3L Fuel System." The illustration shows 57 numbered callouts pointing to components arranged around the engine, including the fuel filter housing, mechanical fuel pump, fuel injectors, high-pressure oil pump, injection pressure regulator, and the network of fuel supply, return, and water drain hoses, tubes, clamps, elbows, and seals. An accompanying legend table lists each item number with its Ford base part number (where applicable) and description. Key components include the fuel filter (9155), fuel pump (9350), fuel injector (9F593) and its associated seals, rings, and gaskets, the high-pressure oil pump assembly (9A543), injection pressure regulator (9C968), fuel injection tube (9A555), and various return hoses (9D308) and fuel line sleeves (9K260). Items that are serviced only as part of a larger assembly are noted with "Part of" references (e.g., injector seals are part of 9F593). A reader can use this diagram to identify individual fuel system parts by location, learn the correct part number for ordering replacements, and understand how the fuel supply, return, and high-pressure oil circuits physically route on the engine. The scan carries a "Steve83" watermark.
