Rubber fuel hose replacement period

[scr0che]

5 years have passed since I had my rubber fuel hoses replaced, and I recall it being mentioned by the engineer that they should be replaced every 5 years?

Just wondering if that is correct/best practice? They look and feel ok, no leaks. I know many of you will say why replace if they're ok, but I want to know what the general lifetime and replacement period is?

At 5 years I wouldn't be rushing for immediate replacement - assuming they are in good condition.
Do check for any splits or cracking (especially near fittings or bends) as well as any wear on the outside, swelling, softening, anything like that.
Considering how cheap the hoses are (for a typical yacht engine at least) you may as well replace them for peace of mind though.
Maybe do it the next time you change the fuel filter as you would then not have to go through the same frustrating bleeding experience twice!

(This is my plan, I'm due to fit a new filter assembly and new hoses all together - the hoses are in reasonable condition but for less than £10 worth of hose I can have peace of mind with very little additional work)

I am just replacing a fuel hose as part of a filter upgrade. I assume it is the original hose and 16 years old. I wouldn't dream of replacing if it wasn't for the upgrade.

The gas pipe on the other hand is getting replaced having just discovered a label saying replace in 2010!

How often do you change your car fuel hoses as part of routine servicing?
I've just changed my boat hoses at 30 years when I changed the fuel tank. There was no sign of deterioration on the old hoses. I think the new hoses are probably better quality as they are all stamped with the appropriate letters for marine use.
Obviously look out for any splits or abrasion where the hose is badly routed.
