Regulated Return discussion
This is a pretty thorough explanation of the factory fuel system. Don't get distracted by this guys headband, he knows his Factory Ford Engineering. Explains some things about the Ford Factory pick up assembly that I think are pretty interesting. Do you wanna know why there is the duck bill on the outlet side of the fuel return? Did you know that the small in tank filter assembly at the pickup/return is actually called the "Thermal Recirculation Module" and that it serves some very specific functions? I wish that the Ford Factory Service Manuals explained what the Ford Engineers were thinking when they designed our trucks!
