HPOP O-ring Replace/Refresh Questions

[_r2h]

Hey guys, my brother recently acquired a 2002 F-250 with the 7.3 PSD. After a few days he developed an oil leak that was quite significant. He asked me for my help as he isn't the most mechanically inclined individual. So, post-crash course into the 7.3L, and many forum threads/posts later, I have narrowed the leak down to the HPOP which seems like a common problem with this motor.

I cleaned the area and block with simple green and degreaser, and appears the leak is coming from the underside of the HPOP (drips down to the valley cover while idling). Short of using a flexible mirror to really get down in there, I can't see any other obvious oil leaks while the motor idling. So appears I'll be pulling the HPOP to service the "non-serviceable" plug.

My daily driver/car I wrench on is a 2003 Corvette, so I'm quite new to trucks/diesels. My question to you fine folks is whether or not it is of value to go ahead and get a whole o-ring kit from bob @ dieselorings.com and just refresh all of the rings + loctite for the whole unit. Working on Corvettes, that is usually our mantra. While in the process of fixing X, might as well replace/repair/refresh/upgrade W, Y, and Z. Just curious to know if that carries over to the 7.3L and it's HPOP.

Also curious to know if I should "upgrade" the the hose fittings to the "new style contains an o-ring at the top to restrict moisture and road dirt from reaching the internal parts of the fitting." Money really isn't an object, when I can prevent these problems from happening again, or significantly delay them occurring again.

Really appreciate any advice/help you fine fellows can offer,
