Would you mind elaborating a bit? Which part of the lines look bad?
That aside, I'd go with factory stuff and order OEM lines. It's actually pretty good. You MAY want to look into converting to a return-less system however, would require updates to your PCM, possibly wiring, etc. Might be a complete PITA unless you have software and want to take on a project like that.
Go to junkyard and pull the lines. It's all pretty well metal to the injectors but the tank side is PVC. I think there's something like 57 PSI line pressure. So if you do decide to switch to something else make sure it can handle say 100 PSI and is compatible with gasoline.
If I was to take on a project making custom lines. I'd upgrade the connectors. I hate the push connect stuff. I'd go with hose nuts... and a locking mechanism of some sort... They probably make a custom hose nut of sorts for fuel lines? It's a bit beyond me, as I've not done that. However, anything has to be better than those push connect clips. They SUCK.
