Plastic vs SS Fuel lines, should I replace the old plastic lines? Options

[billd]

I'm starting my conversion back to EFI and noticed that the plastic fuel lines running through the tunnel are not in bad shape. I'm tempted to use them as is. Anyone on the board have experience with the longevity of these plastic lines? If they are an accident waiting to happen, I'll replace them with SS.

Sounds like its good insurance to go ahead and replace the lines. How hard is this to do with the engine in place? I imagine that makes bending the line along the firewall and up through the tin even harder. Also, do folks recommend using a single piece or using two pieces with an AN elbow fitting at the firewall. A single piece is less likely to leak, but harder to bend into shape.

I did a single piece... not that bad, but no engine in the way... it would be hard, but possible with the engine in place... just have it jacked up enough and it can be done, just not going to be fun.
