Pretty easy to change but you have to know what you are doing. Pump MUST be on full cam to replace o'ring 2.

That the ones either side? Back one by the block is a PITA to access? Seem to recall a spring flies out too?

reading the write up you don't undo the head block totally just the 2 opposite screws to stop springs flying out? or could be wrong
I know when neighbour undone his old one a lot of screws and bits flew out
 
Just follow my guide its fool proof apart from the markings on the top cover not showing up on the photos I took. It must be fitted exactly where it came from.
Mark it at all corners just to be sure it goes back exactly.
If your just doing the injection head then nothing g to worry about just loosen the retai ing bolts only just enuff.
Good luck with it
