How do you re-prime a Kubota T1570 lawn tractor that has run out of fuel?

To re-prime a Kubota T1570 lawn tractor that has run out of fuel, first, ensure you fill the fuel tank with fresh gasoline. Next, turn the ignition key to the "On" position without starting the engine, allowing the fuel pump to run for about 10 seconds to pressurize the fuel system. After that, attempt to start the engine; it may take a few tries as the fuel lines fill up. If it doesn't start, you may need to manually prime the fuel system by loosening the fuel line at the injector to let any air escape before tightening it back up.
