How do you bleed the fuel system on a Massey Ferguson 481?

To bleed the fuel system on a Massey Ferguson 481, first ensure that the fuel tank is filled and the fuel shut-off valve is open. Next, locate the bleed screw on the fuel filter and loosen it slightly to allow air to escape while pumping the hand primer until fuel flows without bubbles. Finally, tighten the bleed screw and check the fuel lines for any leaks before starting the engine.
