Part Numbers For Air Conditioning Hoses. I Am Told I Need The "S" Hose. on 2001 Volvo V70 XC

The AC Just Stopped Working Two Days Ago. The Leaking "S" Hose Is At The Very Front Of Car And Difficult To Get To. Supposedly This Leak Has Caused The AC To Stop Functioning For Lack Of Retaining Refrigerant. It Is Also Possible I Need A "Filter". What Are Cost For Parts.
