the old man needs a hand

Hey wet heads and my ac buddies need a little help. I got called in to help finish a job,,before i get started I just want to say happy fathers day to all you dads out there. I am working on a 20 ton split ac unit. New indoor coil,  new tx valve and new liquid line pump down valve. I just need to find out how much refrigerant is required for a 65 foot lineset/ suction line 2 5/8 liquid line 1 1/8. I have loaned out my old ref manual with all my charts in it.

peace be with you
