I got my repair kit from a dealer because I needed it quick. If you have time, you can get it from Guzzles: High Pressure Oil Pump Repair Parts or Clay at Riffraff.

Binuya,
Thanks for the info. I tried the link to Guzzles and ended up on "orings.com" with this: Does that look like the part?

My leak was from a different plug. If I remember correctly, it was one of the regular plugs in the back of the HPOP and the way the leak ran, it looked like it was coming from the one you have pictured. I traced it by holding clean paper towels back there with the motor running, (and after having cleaned everything very thoroughly). Either way, once you have it narrowed down, you got the right place to buy the needed kit.

OK, on digging deeper, I still can't see where the leak is coming from. All I can tell is that there is a small (couple tablespoons) puddle of oil right behind the fuel filter on the right side of the valley. It must be coming from up front somewhere as the engine is tilted slightly towards the back, and the oil must run down the valley, over the bell housing and blow on the trans and undercarriage. For the most part, the oil pan is dry.
Any ideas how I can pinpoint it?

Best way I've found is to clean the valley area very well, and then once it dries, get up and in there with an inspection light, mirrors, and while it's running, stuff wads of clean white paper towels here and there. This is how I've pinpointed my HPOP leak and HPOP hose leaks.
Any leaks will collect in the valley and exit through a hole in the back of the valley which drops down into the bellhousing area, and out the bottom.

It's really tight in there below the fuel filter and I can't see much of anything usable even with an inspection camera (I bought while I was still employed). And the belt and fan aren't that far away. Is that unit Rich sent (above) of the HPOP more or less below the filter and in the same position as shown?

Not sure what you mean by this...? The HPOP pictured above is in front of the fuel filter. It's reservoir is mounted above it. It is rectangular.

Sorry. What I mean is that the pump appears to be under the fuel filter and not visible from the top. The pump reservoir appears to be just in front of the filter, again blocking any view of the pump itself?

I'll go out there tomorrow and try to clean it up nice, then see if I can see or feel the pump and its fittings, cause I sure can't see it from above.
So there is a way to change some of those hidden fittings without pulling the fuel filter?
