2002, 7.3L Oil Leak

I found oil leaking from the high pressure line on the driver's side of the injection pressure regulator valve. It appears it is leaking where the nut meets the housing. What is required to fix this problem? Any help would be appreciated.

There is a special tool to disconnect the line from the fitting that is leaking....The ford o ring kit comes with a new o ring for each fitting (2) and the plug at the back of the pump....Once the two lines have the fitting undone, you simply unscrew the two fittings and put new o rings on them, locktite the threads,and re install, being carefull not to over torque the fittings...

its an OTC tool that you use to disconnect the fittings.....you can probably build something. It is a U cutout of a metal that is used to get above that blac plastic ring and pry down on it.....then you pull up on the line

Make sure to inspect the retaining ring on the fitting before you reassemble, sometimes they break. Thats also the reason you shouldnt just try to unscrew the fitting from the pump with the line still connected....

The front fitting was loose of all things,I use a crows-foot wrench and tightend it, this has stopped the leak but I think I will get an o-ring kit and re-do the whole thing, makes me wonder why it came loose in the first place, what with the loc-tite and all.

Guess I'll get that o-ring kit real soon, Thanks. Also, any idea what the torque values are?
