Plumbing help please

[Dash]

My husband got me a Sicce return pump for my birthday (this is what happens when you’ve been married for 20+ years). My current return pump generated a bit of noise so I thought this would be a good time to replace the last part of the return pipe with a soft tubing of some sort. So, what is the best kind of tubing to use and where can I get some of stuff needed?
Thinking maybe 6-8” of soft tubing?
Thanks for your help!
