I have a 2003 s-type. I went to put the fuel rail back on. Started the car and noticed a good fuel leak coming from the regulator. It looked as though it was sweating. It was a less than hair line fracture in the plastic body of the regulator. Has anyone else had this problem

 

It's not likely, as few have even taken the rail off. What did Search come back with?

I've replaced this on my car, it was leaking from the 'split' in the body. I replaced mine with a Lincoln part from local dealer, same part number as Jag...saved a few $$.
