First of all, I need to know the kind or model of pump it is, then I can help you.
you turn up the fuel pump
It does not have one. If you need to bleed the lines from running out of fuel there is a little knob next to the injector pump you open to bleed out the air. Make sure you close it about a min after the tractor starts.
it is inside the high pressure pump, which deals the diesel
There is no need to bleed air from a fuel pump.
No, it will bleed itself when it runs.
You should never had to "bleed" a fuel filter. Any air in the fuel line should come out as the fuel pump pushes fuel through the line and filter to the carburetor. There will always be some air or open space in the filter.
Unscrew the fuel caps, insert the nozzle from the fuel pump, turn on the fuel pump.
The earlier Courier's had a primer pump on the fuel filter. The later ones are self bleeding.
That is something that needs to be done by a proffessional. Take it to a shop that specializes in fuel pumps and injectors.
No you do not.
NOT TRYING TO FUNNY THE LINES ARE INTERALL IN THE HEAD AND IS PRESSUREIZED BY THE PUMP ON THE CHASSIS
The electric fuel pump is inside the fuel tank
