Where is the fuel pressure regulator on a 1999 mercury cougar?
it depends on the manufacter date. 5-3-99 had a fuel regulator
with a fuel return, after 5-3-99, no fuel regulator, returnless
fuel system. if it is flooding, look at the fuel pressure sensor
bolted on before the injection rail, fuel line go's to it and has
one vacuum line and one plug in.
