This fuel injector pump system is way to modern in this section. Pop up one level and then enter the Yanmar (NEW) and post over there. I bet several have been in this fuel injector pump system before in the other section here on TBN.

Is it leaking fuel inside the pump or outside when u tighten the holder.??
If it’s inside, u missed the locating pin and sheared it off and the barrel isn’t seating properly..
If it’s outside, u probably need a new holder oring and delivery valve gasket.. Do u know the proper torque of the holder.??
