What tubing to buy for Liquid Pump - 500GPH (12V) ROB-19222

I’m going to buy the Liquid Pump - 500GPH (12V)

I doesn’t come with tubing/pipes/hoses

Where can I buy the correct size of tubing to fit the pump? How do I know it will fit?

Thanks.

3/4" or 19mm ID hose fits.

Hardware store should have it.
