Thinking I remember a funnel end will fit right in the fill hole on the hydraulic and swallow up the fluid pretty fast. You are looking at the attached picture hole?  
I bought Kioti filters from Mowpart. Hydraulic T2185-38031 $35.18, Hydrostat T2195-38031 $21.92. This was April 1st, 2015. I did pay shipping and tax making my total order $71.76. About the same price you paid.
