[C320-list] Aqua Lift Muffler

[bruceheyman at cox.net]

I believe you only have to replace a hose when it is beginning to break down.  With hoses around the engine you can tell if it is breaking down by feeling for any soft spots and if there is a lot of black that rubs of on the inside of the hose after you remove it from a fitting.

I suspect that this is the standard answer from any mechanic in any
industry.  They would rather replace than try to reuse.  Plus, they make
a profit on the replacement part!  And it eliminate any  potential
problems from a subsequent leak.
