Where is the fuel pressure regulator on a 1998 5.0 Mountaineer? How nasty of a job is it to change?

My 02 Sport Trac with 98 Mountaineer drivetrain has suddenly started running real rich, with DTCs indicating both too rich, too lean for both banks and fuel trim out of range.

On the '98, the FPR should be at the right rear corner of the fuel rail, just behind, inboard and below the throttle body elbow.

Only two screws and a vacuum line, no big deal. Very changeable in a parking lot as long as the engine is less than scalding hot.

Starting in '99, the FPR go moved into the fuel tank, a much more involved job to replace!
