I wish I would have known how poorly the repro sending units were before I wasted good money on one. I managed to find a NOS unit at Carlisle last year. It reguired only minimal adjustment and read perfectly on my gauge.

I would have had my original rebuilt if I couldn't find a NOS. Here are 2 places on the web that I found. I have no information regarding their quality of service.
