Fuel pressure reg whinning??

[James H]

Havn\'t used the rex for a about 5 days & came to use her today, put the ignition on & allowed her to prime as always but stright away the fuel pressure reg started whinning thought nothing of it, drove to work got out with the engine still running & it was still continously whinning away ... does this mean its on the way out? Thanks James.
