Electric fuel pump in line or in paralel?...
Rotax instalation Manual presents a fuel circuit with electric fuel pump in line (not in paralel). When electric fuel pump is on, the fuel passes trough the mecanic fuel pump to the carburators. But if some obstruction apears in the machanic fuel pump... Well, tou know.
Even same type of airplaines are being produced by the same cosntructor with different fuel circuits instaled.
So... wich circuit is the correct for a Rotax 912 ULS 100 cv?
