I happened to have a SS Whitey metal-on-metal plug valve laying around which was rated at 10,000 PSI. I put that one in. The only cycling I get is due to temperature. After a hot day, the fluid expands and pressure builds up and relives through the internal RV in the pump. Then when it cools off the next night, the pressure goes back down and the pump cycles for an instant to when the master switch is turned on the next time. Just a reminder: The reason many of us po'-folks chose the Lancair kit in the first place was that we could afford to build it, and afford to fly it. So sure, Lance used the cheapest cra^H^H^H stuff he could find in order to keep the kit price down. Any of us who are unhappy with what he provided are free to upgrade, as I have done a number of times. That's probably why I am not flying yet ... >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML homepage: http://www.olsusa.com/Users/Mkaye/maillist.html
