Open the engine access door on the left side of the machine.
Turn the priming pump plunger counterclockwise and pull out the priming pump plunger.
Operate the fuel priming pump in order to fill the new filter element. Continue to operate the fuel priming pump until the pump resists operation. This indicates that the filter element is full of fuel.
Push the priming pump plunger inward and turn the priming pump plunger clockwise in order to lock the priming pump plunger.
Start the engine. Look for leaks around the filter element. If the engine will not start or the engine misfires, more priming is necessary.
If the engine runs rough after start-up, continue to run the engine at low idle. Run the engine until the engine does not run rough.
Close the access door.
