Are you talking about the HPOP itself or the HPOP oil reserviour?

I don't know what year you have but I just changed one of the O-rings on my Excursion this week. It was on the drivers side and fairly easy to get to. I used the $12.50 kit plus $2.50 for First Class postage. I am posting a link to a more complete kit with probably all the O-rings in your pump. I would call them up (Riff Raff Diesel)and send them a picture of what you need. That is what I did. Good luck.

Whats under that threaded cap is the spring for the hpop overpressure relief valve, but I'm just a noob so what do I know?
