fuel sending unit wiring
« on: January 24, 2010, 11:42:19 AM »
 ??? I have a 66 mustang and while rebuilding I noticed why my fuel gauge is not working. The previous owner removed the wiring from the tank to the gauge.
Is there a replacement for this wiring or can I wire it myself. Hard to find just this wiring without buying the entire electrical harness. Appreciate any help in this direction.

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.

I agree with Jim.  Just replace the entire rear end wiring harness.  I replaced mine last year.  That old 45 year old wire is adequate at best.  It's really an easy job.  Just take off the kick panel, scuff plate and rear seat side panel and you will see the entire harness that leads back to the trunk area.  Not only will you have some pride in doing it yourself, you will always pass your state inspection as well.

Thanks for the advise. I'll probably do the rewire at the tail lights. Sounds like a good thing to do. I already had to duct tape and zip tie the engine harness to get it to run. Sitting in guys back yard for over 20 years. thanks.

You need to bite the bullet and begin replacing wiring harnesses.
