just done this myself . about 75% of the steps do not need to be done . if i was do do it again i would leave out removing thefollowing
remove fuel pipe unions
remove pressure releif valve
remove the end plate (the one with bleed nipple on)
all the above are just for cleaning , and it it has just come off a running engine (mine had) then it will be clean as petrol is 1 of the best degreasers in the world , plus you would save about a hours work , tuning the job into a half a hour job . plus as you are breaking seals there is more risk to leaks .
my 2p's worth anyways
