You only need an equalizer tube if you are using an *expansion valve* if you use a fixed orifice metering device you do not need an equalizer tube.

beyond that, you can drill a 1/4" hole in the suction line just before it exits the A coil and silfos (a type of silver brazing rod) an equalizer tube in there.

Please rate my work, it is how I earn a living and does not increase your charges, in exchange I will hold the question open for any follow up you need.
