Where Buell did have a covering on this short loom they used the expandable type loom covering. This would allow easier fitting over the electrical ends - back in the ancient past when I first did this repair on my old '06 Uly I did cut the wires to allow a smaller diameter heat-shrink over the wire, solder and then cover the join and the worn nick with heat-shrink.
I also used some small cable ties as spacers to hold the loom in that groove in the extrusion and keep the wires away from the metal edge - that extrusion can do with a quick touch-up with a small file as it usually has a very sharp edge.
I pulled that pump again after another 30,000miles and that original repair was as good as they day it was done.
Another suggestion for a quick, non-invasive repair would be a length of small diameter fuel line slit lengthways and fitted over the wires and then that fitted into the groove in the extrusion?
