Replace all the O'rings. It's doubtful it's the gasket as the gasket is under very low to no pressure. Dieselorings.com sells a kit of o'rings. Replace them all, and get the "non-serviceable" plug replacement. All the o'rings on the hpop degrade. You will see what I mean when you take it apart. Use Viton 90 o'rings and you won't have this problem again. The non-serviceable plug is supposed to be replaced with the pump on the bench, but it can be done with the pump on the truck. The surface tension of the oil will keep the little plastic check ball in place. Just don't blow into the pump with the plug out. The plug came right out in mine. No need to heat, or anything. Where I had problems was one of the pump mounting bolts was seized and I could not get it loose. If I ever have to replace my HPOP, I will have to cut the pump to get the passenger side mounting bolt out ...
My leak started with the lines, but soon after the non serv plug and the drain plug at the back was leaking too. The IPR oring also had issues. They all looked like they had partially dissolved.
