Yes. You can not see the inside, or how bad they are worn on the outside.
The corrosion can weaken the line and cause it to ruture at any time. You
just can't tell.

Go as far as you can with the strait lines and then add flex line to the
ends. They can be flexed to fit in place and come in many sizes. You can
get custom ones made, or do it yourself, but the custom will cost a lot,
and yours may leak.

You can do it, but the pressure fittings applied at the factory are
supperior and look better in my opinion.
