Does anyone know the pressure between the mechanical pump and the injector pump.
And maybe an idea on the volume? It seems like there is little discussion on the mechanical pump.

Very low pressure, almost non measurable.
and low volume.
Neither of which is an issue as the engine uses very little fuel per min.

My problem is that I keep getting a red light and and low rail pressure code. Turn off tractor and back on and it runs fine until it gets loaded with the mower in tall grass. It will run fine if I don’t load it. New filters, clean system and new fuel. It starts immediately. I guess i’ll try a new injection pump next.
