Phil, Thanks, I have not had a unit out in a log while to know what it looked like.

Thank you again Marc for letting us know of the alternative part and Phil, thank you for posting pics of your install.

This is probably what I will do.

Hi Phil,

Which end of the float did you shorten? I should probably service my pumps (I have not touched them at all) and might fix the float at the same time as I think that is not accurate anymore

The end of rod that inserts into the sender. Had to cut off the existing 90 degree bend.

Hi all,

I started this thread a little over two years ago. I just wanted to finish it up and say that last month, I took out my fuel sending unit with the intention of getting it fixed (it wouldn't read the fuel level correctly).

After calling to inquire and ask some questions, I sent my fuel sending unit to Tri Star Radiator, LLC in Seneca Falls, NY (http://tristarrradiator.com/). The business is run by Dan & Samantha Hora (very nice people to work with). The Hora's are very busy and did have about 4 weeks of work before they could get to my sending unit. When Dan, got to my unit, he called me to tell me what was wrong (from memory, I think that the ohms on my unit were reading about 14 off).

Anyway, I got my sending unit back last week and installed it back in the car this weekend. It now works like new!

Because I wanted to post a follow up to this thread, I asked if they could send me a summary of what they all did (there was more than one issue). Here is there summary:

"Hello Jeff. Samantha here. Here is the basic rundown of what we did to rebuild your sending unit. First we disassembled and cleaned it up. We have a mixed media blaster that is very gentle with delicate parts but effective at cleaning rust and debris. Then we rebuilt your rheostat (fuel level sensor). We then went over all connections, and rewound, sealed and soldered them. After this, we modified your upper wiring harness so that it will not be prone to future issues like many of these units are. Lastly, we left your unit unpainted at your request. We usually ask the customers preference because we have rebuilt MANY sending units that are then submitted for judging on regional and national levels, so we know how important some of those labels and part numbers are. The epoxy paint that we use to coat the tops of the units to retard deterioration due to the elements, does obscure those fine details that can be important in a competition. Hope this helps and if you have any other questions, feel free to get in touch. Have a terrific weekend!"

Anyway, I also had them install a "Y pipe" type elbow that Carter here on the forum machines. I haven't posted pictures on a forum since the "Photobucket" debacle, or I would post a pic (I haven't taken the time to learn the new way.

The point of my post and thread IS: If you want your stock sending unit refurbished to "like new" operating condition, try Dan & Samantha Hora at Tri Starr Radiator (sendingunitguy@gmail.com)!

Good info.. what type of cost we they for that work?

Meanmyz · 10-07-2020

It was $219 with another $22 for Fed Ex back to me for a total of $241.

seems reasonable considering what they are doing to it
