Yes and Yes.
You will need a 14 mm wrench for the lines, an allen (size long forgotten) for the pressure valve holder lock rings, new o-rings and new pressure valve seals -- the part numbers are listed somewhere in an old thread. You will also need some antisieze. A splined wrench for the pressure valve holders is required, there is no substitute.
Process:
Clean all the dirt off the IP and lines.
Remove injection lines at injectors and pump, lay aside (no need to actually remove from car).
Remove lock rings by taking the screw out for each pair. Likely to be stuck.
One by one, remove the pressure valve holders. They simply unscrews. Watch for the pressure spring that sits on top of the valve instert, it tends to stick in the holder, then drop on the floor.
Remove o-ring from holder, install new one, then use a pick to lift off the copper seal on top of the pressure valve body. Make sure everything is clean, then put a new seal on top, put the spring back in, and re-install the pressure valve holder.
When you have them all in, torque to 25 nM twice, then to 30 nM without loosening. If you don't have a torque wrench, this is a firm pull, no more.
Re-install injection lines, leaving the injector nut loose.
Crank engine until all the air is out of the injection lines.
Tighten injector nuts and start car.
Caveats:
No grit in the IP, make sure EVERYTHING stays perfectly clean. DO NOT pull the sleeves out of the IP if they get dirty, use some carb or brake cleaner to blast the dirt off!
Don't loose the spring inside the pressure valve holder!
If you don't get the torque correct, the seals will leak, causing running troubles but no other damage: Hard knock and rough idle with no smoke, but engine runs fine at high rpm indicates leaking seals. Just retorque the affected holder, should fix it. At worst, you will need another seal
If you can lay your hands on the spline socket, this is easy.
