Dee, I agree with Rob... I too, do not have a check valve, and fuel flow is dictated in the Posa Injector, by the opening of the mixture control lever. If you notice, the fuel entry to the injector is through the mixture valve. To properly set it, make sure that when the mixture is fully retarded (pulled back) the mixture valve is fully seated in the closed position, then while cranking to start the engine, advance the mixture control and fuel will start flowing to start the engine or likewise, crack the mixture valve when you are doing your initial 5 prop turns by hand as we discussed earlier for a quick engine start. To ensure that no fuel is flowing when securing your airplane at the end of your day, retard your mixture control and shut off your main tank fuel valve also. Just keep it simple.

The VW fuel pump will not flow fuel if the engine is not running. The electric backup fuel pump cannot push fuel through the VW fuel pump. So, had to put the check valve in parallel with the VW fuel pump to get fuel to the carb for starting.
