Got a good one this week. 2001 cougar 2.5 return less fuel system. Fuel pump cycles with fuel coming out of the module,the fuel filter, but not to the fuel rail. I replaced the fuel rail pressure sensor thinking this was the problem. I un hooked the fuel line from the sensor and no fuel comes out. Before I try blowing air through the lines, do any of you know what this thing actually is? To me it looks like another fuel pressure regulator of some sort, but I get no information about it from my ford service manual or the internet.
