WARNING This is a serious building Error!
The problem is that the boost pump should be in series with the engine driven pump. I highly recommend you re-plumb this aircraft correctly. The boost pump will push fuel through the engine driven pump before starting, and will give you a pressure bump when turned on with the engine running.
In cruise flight the engine driven pump will pull fuel through the boost pump. In the event of engine driven pump failure, the boost pump will supply fuel to the engine pushing it through the engine driven pump.
The primary reason EAB aircraft crash early in their testing is fuel related problems like this one. The fact that this aircraft has flown successfully for years could be dumb luck! Please fix this!
