I am replacing the A/C suction line,that was leaking,that runs from the front of my E350 van to the rear air. Do I need to add any refrigerant oil to compensate for the oil in the line I am replacing? If so how much.

During normal A/C operation, oil is circulated through the system with the refrigerant, and a small amount is retained in each component. If certain components of the system are removed, some of the refrigerant oil will go with the component. To maintain the original total oil charge, it is necessary to compensate for the oil lost by adding oil to the system with the new part

Refer to below fig. for refrigerant oil adding amounts and methods of installation.
