Henry:

You will need to get new clips for the injection lines -- they are plastic and will usually break when you unclip them.

Unclip the plastic clips, take the capnuts off, then take the injection lines off the pressure valve holders. Next, remove the lock rings on the holders.

You will need a special splined socket for the holders themselves, there is no substitute. Remove the holders, careful not to use the spring on top of the pressure vavle. The copper seal is on top of the seat inside -- lift off with a pick or small screwdriver, replace spring and holder, and torque to 20 lbs two or three time.

Re install locking rings, injections lines, and and retaining clips and start.

Pretty easy, and the seals are $7.60 for both copper seals and new 0-rings.
