Those contemplating doing the HPFP yourself, it's not so hard. I had the Bentley manual handy, which is always great on any repair.

A few notes:

- Gas can shoot out as you're removing the lines. Be careful and wear eye protection.
- I didn't need the special MINI tool to release the fuel line. I used a couple small screwdrivers to press in the plastic tabs (which promptly broke off). Then I rotated the fuel line so one of the tab holes was pointing up, and used one mini screwdriver to hold the plastic sleeve in place, then pushed it forward then back and it popped right off.
- I didn't buy a new high pressure fuel line
- I didn't remove the low pressure line at all as prescribed in the Bentley manual. That step would have required going underneath the car, but since I didn't need to do it, the entire repair was done from the topside of the engine. Of course, I had to disconnect it from the HPFP being replaced. That's the quick-connect that didn't require the special tool.
- I didn't remove the intake manifold at all (what the hell Bentley manual????) The lower part of the HP fuel line attaches back there, but is accessible without removing the intake manifold.
- I did remove the air box and the upper hose that leads away from it (that branches into the valve cover)

All in all, it's pretty easy if you're good with a wrench. It's all topside, uses standard tools, and is a basic unbolt, re-bolt kind of repair.
