Step-by-step guide to changing the fuel pump
Here is a step-by-step guide on how to change the fuel pump on your John Deere 6420 tractor:
Step 1: Drain the fuel tank
Before attempting to change the fuel pump, you need to drain the fuel tank. This will prevent fuel from spilling out when you remove the fuel lines. Use a fuel transfer pump or siphon to empty the fuel tank into a suitable container.
Step 2: Remove the fuel filter
Locate the fuel filter and remove it using a wrench or pliers. This will allow any remaining fuel in the system to drain out.
Step 3: Disconnect the fuel lines
Using pliers or a wrench, carefully disconnect the fuel lines from the fuel pump. Be careful not to damage the fuel lines as you remove them.
Step 4: Remove the old fuel pump
Using a ratchet and socket, carefully remove the bolts that hold the fuel pump in place. Once the bolts are removed, gently pull the fuel pump out of the engine compartment.
Step 5: Install the new fuel pump
Place the new fuel pump into position and secure it with the bolts you removed in step four. Be sure to tighten the bolts to the recommended torque settings.
Step 6: Install the fuel filter and reconnect fuel lines
With the new fuel pump firmly in place, it is time to re-install the fuel filter and reconnect the fuel lines using pliers or a wrench. Be sure to tighten the connections properly to avoid fuel leaks.
Step 7: Refill the fuel tank and test the system
Now that the fuel pump has been replaced and all the connections have been reinstalled, refill the fuel tank and start the engine. Test the fuel system for any leaks and ensure that the engine runs smoothly.
