Final Bleed and Start Tractor

How Garbage Biodiesel Ruined My Classic Massey Ferguson Tractor (And How I Fixed It)
What happens here
With the rebuilt injection pump installed and all components reconnected, the creator performs a final bleeding of the fuel system. He loosens the injector lines one by one and cranks the engine until a steady stream of fuel flows from each, indicating that all air has been expelled from the system. After confirming proper fuel flow, he tightens all injector lines. He then successfully starts the tractor, which runs smoothly. The creator shares a 'pro tip': always ensure the kill switch is fully pushed in (disengaged) after use, as it can get stuck in the 'off' position and prevent the tractor from starting.
Goal: Successfully start the tractor and confirm proper fuel system operation.
