1994 Ford Fuel Delivery Systems - In-Tank Fuel Pump Assembly Diagram (9A-5)

This is page 9A-5 from the 1994 Ford Powertrain Control/Emissions Diagnosis manual (dated July 1993), covering the Fuel Delivery Systems (FDS) section, Component Description. The page explains that electric fuel delivery systems vary by vehicle and model year and are classified as Type 1 (Single Tank: single fuel delivery assembly or in-tank fuel pump assembly) or Type 2 (Dual Tank: one fuel delivery assembly per tank). It lists common components required by all systems: a fuel pump with discharge check valve, a reservoir around the pump inlet, a fine mesh fuel filter, a pressure regulator, supply and return tubes/hoses, a fuel tank, and a fuel supply manifold or fuel rail feeding the injectors, with the Powertrain Control Module (PCM) controlling pump power and injector timing. A subsection on the Type 1 in-tank fuel pump notes its discharge check valve maintains pressure at shutdown, and mentions the 3.0L Taurus FF pump's extra fuel line tap for tank draining. Figure 1 (illustration A16317-A) shows a typical in-tank fuel pump assembly with labeled electrical connections (pump positive/negative, sender positive/ground) and components: fuel supply, fuel return, gauge sender, pulse damper, fuel pump, fuel intake sock, and float.
