That's some good mark up! A foot of viton hose last I saw on the net was like ~$12 depending on diameter. The teflon SS braid hoses are maybe $20 if your hose shop isn't very friendly.
Where do all the small pieces of viton go?-popcorn
I think I might start my own ebay kit and sell it for 100. when I replaced mine I spent $27 for SS braided teflon. I did not replace the small pieces and have had no issues. I believe they go to the hard lines around the filter bowl.
