I have all now I need to check high and low sides and have verified the system is sealed with a vacuum.

I need to know high and low side pressures for my ac system so I don't over charge. Please help. don't have the money to pay someone else to recharge the system.

 

its not pressures you are looking for, they will always be different, what you need is weight, it should be on one of the stickers under the hood, if using the standard 12oz cans, it comes right at about 3 cans
