We need a tank teardownHi. Does anyone know why the pumps have a suction jet attached to them? That's the extender arm that is clipped into the pump housing and reaches towards the front of the tank. While the pump sucks fuel from its floor through the mesh there, according to the diagram the suction jets cross over between the two sides. I wonder where the fuel really flows. I also wonder if the regular shouldn't always send some fuel back into the tank, which would require the pump pressure to be higher than the calibration of 4 bar?
Has anyone run this system outside the tank and can comment on these aspects?
