Dual tank fuel lines and Harness
 

I have a complete dual tank set of fuel lines (between tanks and selector valve) and wire harness from an 84 C30. The lines are in good shape, the harness feels a little stiff but it worked when the truck was running. If you are interested in the lines and/or the harness, make an offer. I won't sell individual lines, so you have to take them all if you want one.
