Here is a guide to help understand the HPOP if you have not seen it. Pretty good info and a few cutaway photos.

If you have a leak from the "Non-serviceable" it can be fixed, but only after removing the HPOP? That doesn't mean you have to replace the pump, right? Can a novice remove the pump and remove the plug, or does it take special tools to service the "non-serviceable" plug?
