Replacing AC compressor and other parts.

I will be replacing my AC compressor and other AC parts on my 09 Tacoma. A dye test shows leakage at the compressor, been empty for a couple years. If I buy a compressor with oil already in will vacuuming system remove that oil? Will I have to add oil again if I vacuum the new oil out, or should I buy without oil and add oil after vacuum?
What components should I get to replace to be assured of the longevity of the AC system?

 

Personally, I would just install the new compressor and be done with it. Rent a vacuum pump from autozone for free and hook up vacuum for an hour then charge up using those cans with the idiot gauge. Very little chance of vacuuming out the oil of a prefilled compressor. I did this same process swapping a leaky condensor on my '08 Rubicon a month ago and ac working great in current 100 degree days.

 

I would also replace the dryer/accumulator. Then pull a good vacuum and refill accordingly.

 

Don’t use the shit cans from the auto store repair your parts and get a proper service from a real ac machine
