just an FYI for mooneyspacers.  Talked to Brittian today and they recommend 7/32" windsheild wiper hose for the lines under the dash from turn coordinator to pilot valve etc. I had my pilot valve tested and as I suspected it was holding vacuum and making my plane very John Deere like.  asked him about sending me some new lines to replace the aquarium tubing thats there now and he suggested just going to the auto parts store and getting the wiper lines.
