I would be inclined to believe that the stub end of the wire is either in the trunk or clipped off at the grommet at the front right hand side of the trunk floor under the car. That means splice or new. The tank end is a special fitting that presses on a screw thread stud like the one on the distributor. NPD sells two replacements, 14405-1 $79.95 - requires 2 pigtails for taillights (13A408-1B $19.95 pr); 14405-1E $92.95 complete. The harness contains brake, tail, backup as well as the fuel line. It runs from behind the left hand drivers kick panel under the door sill to the trunk area. I would recomend doing the full replacement as vice grip splices are crap.
