Hi Wayne, It's a 1984 - first year NS.
Andy, my thoughts exactly - I suspect it was a bit of over-engineering. The fuel pump is definitely correct for the NS; there is a special tab cast in the frame to mount it on, there is a molded rubber cushion, and the lines have dedicated clips and retainers to hold them in place. They look like this one, a common 4-stroke pump for the same years:

I studied the system, slept on it 2 nights in a row, and have decided to run the fuel line directly; it would only be about 8 inches long, and could be routed so it's down-hill all the way with no loops or 'traps' to prevent vapor-locks. I would think that the NSR requires even more fuel than the NS. I will include the old pump and sundries in case someone in the future decides to do a Concourse-accurate restoration.
