Thanks wooble, Stephen and Paul - I've got the cradle off (bolts were OK) but when:

"it's then a matter of loosening the clamp holding the filter and the unions (use caution as there's likely to be petrol spilled here - best to have a bowl under the filter and if possible rags round the unions when they're loosened), marvel at the black petrol that comes out of the old filter and fit a new one in its place" [wooble]

how do I hold the filter sufficiently to undo the nuts [as it's not conveniently bolted to the bulkhead] ? I've WD'd the unions to start loosening them up, and will try to get them off (or pay somebody else) tomorrow.

I've also bled a little muck-containing fuel from a valved bleed tap on the injector rail, and - while outside the house - is running a little smoother, but may be stopping once I take it round the corner. At least it's not hunting so much as it was a week ago before I cleaned the plugs and closed up a couple of gaps.
