Shifting gears, what about PEX for water lines? Easy to install and repair and I like the idea of freeze protection when there's an early cold snap. What say ye?
PEX I have used for years in houses but original used them for the manifold system ( breaker box for water control)

like this

36144 - Viega 36144 - 1/2", 14 Port Compression MANABLOC (6 hot, 8 cold)

But not worrying about stuff like that would eliminate more than half of all boating related internet traffic.

Nah...you and me could entertain each other for hundreds of posts per day dreaming up what can go wrong with our boats!

Thanks again, folks. I'm going to go with copper on the fuel lines and replace water lines with PEX as necessary, or when installing new. To be clear, I'm less concerned about burning through a fuel line than I am of a bilge full of diesel as a result of using the wrong pipe or hose.

Worth every penny of the cost! It pays for itself in the first hour if your labor and aches and pains have any value at all.

I really like the Qest or the Sea-tech fresh water fittings systems instead of PEX; no need for special tools and makes doing additions or temporarily removing an item from the system easy.
Got great customer support from Sea-tech when I was doing a project.
