^ There's no fuel pressure test port on 05+ Duratecs. I'm not sure about the earlier PZEV models. Ford's factory service manual recommends cutting into the fuel line under the hood to install a mechanical gauge. I'm sure dealerships have something rigged up handy. However, because of the way that the system works- a fuel injection pressure reading doesn't really tell you anything. In case you didn't know, Ford's EECV systems don't have return lines, or fuel pressure regulators like EFI nuts are used to. The system's pressure is dictated by demand, and the fuel pump's pressure is regulated by the computer increasing or decreasing voltage to the pump as needed. That's what the fuel sensor in the center of the fuel rail is for. It should be a more efficient system in theory, but in reality it's minimally better at best.
