How often do you change your engine hoses and if you have done so was it because they were leaking, had visible deterioration or just because it seemed prudent to do so?

How often do you replace the hoses on your car?
Never I suspect.

My Yanmar 3GM30F was bought new in 1999 and has done 2700 hours since. It is still on the original hoses.

I had to change the originals on my VP diesel. Not because they were unserviceable, but as they didn't carry an ISO imprint it was a BSS fail . VP originals didn't either , had some made up.
Another example of the stupidity of BSS box tickers !

Fuel or coolant hoses?

Fuel.

As per another thread, I would regard fuel hoses as 'secondhand' at say 10 years old and probably outstaying their welcome at 20.
They become less supple, so harder to seal reliably, a long time before they break up.
If they get hot or exposed to fluids, they could age more quickly.

I replaced the fuel and water hoses on my VP 2003 after 20 years. Purely precautionary, the hoses were developing some external signs of deterioration (few surface cracks). Not difficult or expensive.

I haven't done mine, yet, having just bought the boat last year. However, for flexible fuel lines in a tough environment, I think I'd be changing lines to neoprene stainless steel braided with aeroquip style fittings. They essentially last forever and are less prone to splitting, airleaks, stress/age cracks or the vagaries of jubilee or crimp hose clips.

Fix as fail for me too. I'll change them if they are perished or chafed before they break, and will do the calorifier hoses every 5/6 years (or whenever I realise that I can't remember when I last changed them usually means it's time 
).
I probably don't need to replace the calorifier ones that often, but having seen a few failures in that area over the years and as it's silly easy to do on our boat it's a no-brainer.

I changed my fuel hoses this week. I had no idea how old they were but they were cracked and might have been sweating diesel. Note that there is a marine grade for fuel hoses which gives a longer fire resistance time than standard automotive.
