fuel pressure regulator

I changed it a few weeks ago and I have to say that it was by far the most awkward thing I 've ever done on any car.In hind sight I should have taken the inlet manifold off first but even getting the fuel heater unbolted was a nightmare and due to me having HUGE hands,I had to dismantle the regulator in position so that I could get the fuel heater up far enough to undo the push fit connector from the top of it.I got there in the end and the leaking has stopped but I'm minus a fair bit of skin and the bruises have started to fade.
The performance has now improved noticeably due to the engine getting the right amount of diesel.
