This one isn't DDEC , mechanical only . I located the check valve yesterday , 1.5 ft from tank outlet as stated . Newell  provided an access port for the tank fitting , but valve looks tricky. Removed hose from tank , connected electric pump and pumped fuel from separate container . Watched bowl on separator,  air bubbles coming through the turbine . Once bubbles stopped I pumped a little while longer , then reconnected to tank . Primed at secondary filter previously . Engine started up , healthy idle . Ran probably ten minutes, I was beginning to think it was on it's way when tone changed . 
If I can get fuel delivered ,I want to try filling the tank and pumping more fuel forward to try and purge all air . After that , new hoses and check valve . And ball valves .
Thanks for input , any comments appreciated.
