This document is an exploded parts diagram of a diesel fuel filter housing assembly, uploaded to the gallery of a 1997 Ford F-250. The illustration shows the filter housing bowl and its associated valve body with callout arrows identifying each component: the filter vent with its O-ring, screen, and orifice; the pressure tube (Schrader valve); the fuel heater; the water-in-fuel sensor; the return-to-tank fittings; the spool valve; the cylinder head return ports; a large O-ring; the orifice return; the fuel bypass (recirculate) hose; the regulator assembly; the nylon screen; and a strainer assembly noted as applicable to the 1995 model year only ("95 MY ONLY"). Several O-rings and seals are highlighted in red, and the nylon screen element is highlighted in yellow, presumably indicating serviceable or commonly replaced parts. The lower portion shows the strainer/regulator stack exploded from the housing base with its threaded cap. A reader can learn the names, locations, and assembly order of all major components of this fuel filter/water separator housing, which is useful when disassembling, cleaning, or resealing the unit. The image carries a repeated "Steve83" watermark. No part numbers, torque specs, or explicit vehicle/engine identification appear in the document itself beyond the 1995 model year note for the strainer assembly.
