Success!!

Smacked the IP collar and flat surface of engine block with hammer and chisel on one stroke.... permanently marking initial position.

Loosened 3 - 13mm nuts on the collar and one 13mm bolt behind on pump. Then unbolted fuel pipes at injectors, 17mm. Rocked the pump towards the engine 1/8" which is all the pipes would allow before colliding with valve cover and then tightened up the 13mm IP nuts 'n bolt.

Hairiest part was bending the pipes by hand to accomodate new position of the pump, after removing 8mm spacer bits and loosening fuel pipe collars (17mm) at the IP.

Tools required include 12 pt. 13mm socket and spanner, 8mm and 17mm too. Toughest nut is the IP collar nut closest to the block. Jammed the pipes apart with flathead screwdriver on reattaching the 8mm spacer bits, of which I omitted reinstalling 2 as redundant and unnecessary.

Results: NO more cold start blue unburnt fuel smoke, improved acceleration and smoother idle..... engine sounds 'happier' with steadier idle and at idle the oil pressure guage hardly flutters at all, where it used to tremble a bit.

Total time spent was 3 1/2 happy hours working as slowly as possible doing lots of misc cleaning chores in the engine bay.
