Vitron hoses. Empty fuel tank and clean in tank strainer, replace fuel filters.
If your fuel lines are not old you can wait on replacing them but over time they will start to leak. I think the main thing is starting out with a clean fuel tank. The biodiesel will disolve anything in the tank and clog the filters. There are fuel treatments that will help but if you clean the tank first you will be ahead of the game.

Good luck. You will notice how it quitens the motor noise down. Your milage will suffer slightly but I can live with that trade off.
