Pressure test fuel system ( 4 hrs )
5 lb can of white desiccant arrived, used approx 1/2 in engine dryer container. Ready to use now. Completed prep of 2" SCAT hoses for heater per Steps 1-5, Sect 48-05. Checked left fuel system w/ Valve in Off position, from Wing Root to Servo for leaks. Held 30 psi air pressure as well as no signs leakage with soap bubbles at connections. Repeated for right side. When I turned fuel valve to Left tank, I found gradual loss of pressure over 30 mins. I soaped all joints...can't find any leak point with soap bubbles. Going to repeat soon and inspect again...Need to cap off opposite side at Wing Root to insure no internal leaking from Left to Right side inside Fuel Valve.
