I'm buying a used Kubota-powered 3 cylinder diesel Grasshopper 925D.

During the demo at the guy's house, he ran out of diesel fuel (he's 80 years old, so I gave him 17 benefits of the doubt)

After refilling, tons of air bubbles were seen through the clear tube that carried fuel back into the top of the tank.

How do i bleed the air from the lines and/or from the injectors because it was running GREAT before he sucked it dry and now it's sputtering and spewing!

Thanks!

You have to crack the injector lines loose at the injectors and crank until diesel fuel pushes all the air out. By loose, I mean just enough to let air out. The last thing you want is diesel fuel spewing all over the place. Do the injectors one at a time and be prepared to tighten the injector line quickly when it starts. Or kill the engine when diesel comes out, then tighten up and restart.

Undo all of them, turn the engine over, when you see fuel coming out redo them up.
