Well after a recent leak off test revealed 3 fugged injectors so i am planning on removing them tomorrow so i can swap them for 3 reconditioned ones, as swadlicote want mine before they hand over the fresh ones i want to make sure that i spend as little time in the morning removing them.
I have the correct socket and crows foot adapters so i am presuming the process would be as follows.
1. remove injector plug
2. remove union pipe
3. remove injector seal
4. remove injector

There are a few things i am unsure of though, first is the system pressure. The car hasn't moved since 19:00 tonight so i expect that the pressure has dropped over night or do i have to remove any regulators/relays ??

Also what is the best way to cap the common rail feeds where the union pipes go, as they will be of the car i want to make sure that no dirt gets into the rail for obvious reasons.
