Driver's tank and all old lines are out!
Tank and straps are in pretty good shape for being 35 years old. No serious corrosion.
I already have the 20 gal '87 tank to replace this 16 gallon tank. Only going to run a single tank - in 6 years of owning this truck I've never used the passenger tank, so I'm just going to drop it and leave it out.
I'm going to keep the wiring in place just in case I ever decide to add it back in again. Looks like I can just splice into one of the wires in the harness for the sender. I'm going to run the power from my relay down the frame in the same location as the existing wiring, and reuse the split loom.
