yes the compressor will come complete with a full charge of oil.
there are 3 tubes comming out of most ac compressors.you have a small one called the hi pressure side. and a larger suction line called the low side.then you most of the time have one more large tube by itself that is used for fill purposes.,
now i am going to show you a pic of my new one.one the left you will see the fill tube.on the right you will see one larger tube(low side suction) andone smaller one marked hi side.now the gauges will connect to scrader ports i will solder inline in on the hi and low side to charge and monitor the system.
hope this helps
