Move header tank out of way
Remove the plugs
when refitting be gentle with the 'o' rings and lub them with washing up liquid to make them easier to fit.
do not force them or they will trap/kink.
when fitted, turn engine on to prime fuel pump. With plugs removed check no excesive fuel is coming out of plug holes. If you have an FPR check it's reading pressure as normal
Then turn over over with plugs removed and check again for no excesive fuel coming out of plug holes.
this will confirm that they are sealed
Refit plugs and fire up.
If engine stops or locks during cranking you have a leak and 1 or many bores are now full of fuel. There is a risk of bending a rod if this happens. RobEvo5 done this but got away with no damage.
