I don't know, everything I have read on this subject suggests it being as close to the motor as possable.
Some say use the vacuum line some say don't, makes it confusing!
Some say using the vacuum line can put a vacuum on the cell and lower the boiling point of the cell. Or could cause the cell fluid to be drawn up into the motor.
P.S.

Mother Nature educates all of us that are teachable. She's hardest on the ones who refuse to learn. Punishment is automatic, immediate, and without pity.
