It's always a good precaution to replace all four sections of
rubber line about every five years.

John Connolly (Aircooled.Net) advises-

I strongly recommend cloth braided fuel hose. Every 6 months, you
should inspect it! Bend it over 180 degrees, and if it cracks or is
stiff, REPLACE IT. Leaking fuel hose is the #1 cause of those
smoldering VWs you see on the side of the road. Don't be a statistic!

Yes. Change it often even if the car is sitting and not driven.
