I think my fuel is leaking because it's wet around the black fuel lines. Where else could this come from? Is there a cheaper alternative to the factory fuel lines?

This is a common issue. I recommend Viton® fluoroelastomer return line, 1/8th diameter. You can buy it at mcmaster. You might also want to buy some 4mm diameter vacuum lines if your lines aren't in good shape.

The viton is really only needed if you are running biodiesel or blend, but these are cheaper alternatives to the factory lines.
