Last year the Cummins mechanic mentioned that I had some cracks in the hoses on our 6BTA's.  The engines are 2000's and have about 800 hours on them.  Could just replace the lines that are cracking or with engines that are 15 years old replace all hoses and fuel lines at one time and be done with it.  

What are your thoughts?  

Thanks

I have changed all of them at the same time twice (current hours / 2945) on my '01 35 Open.  And inspect the "hard" ones underneath also.  It's not just the engine hours, it's the "marine age" we use in maintaining my boat.
