What is the brand / manufacturer of the gas gauge used in the '32 REO FC? Is there anyone who rebuilds or repairs these or any info available on how they work? Thanks!

King-Seely Telegauge. Page CH-1 in the REO Mechanics Instruction Book. (eBay if you don’t have one)

My brother “rebuilt” several of these units. Most were from ‘33 & ‘34 Fords and one from my 1929 REO Flying Cloud. The major issue was that the original fluid had dried up inside the small copper tube running from the glass sight tube to the large vertical tube mounted on the rear of the gauge. You can test this by trying to blow through the tube by mouth. If you can’t the it’s clogged. You might try using a ultrasonic cleaner to try to get the old gunk out - but that’s not what he did. His technique is not for the faint of heart. He unsoldered the small tube and separated it from the base or the large hex shaped tube. From there he was able to mechanically work the gunk out of the tubes with fine wire, or in his case a hypodermic needle. After he was satisfied that it was clean he then resoldered it back together. This is tricky as solder tends to wick and if you are not careful it could be “sucked” into the tube and block it. However this technique will work. Also, make sure that you reuse the original nut that attaches the pressure line that runs to the gas tank because the threads on the large hex tube are an odd number - either 26 or 27 or even 28 threads per inch (I can’t recall) and reproduction nuts are made assuming that this thing is a standard size - which it’s not. Another word of caution: DO NOT OVER TIGHTEN THE NUT FROM THE PRESSURE LINE BY USING A WRENCH OR YOU WILL BREAK IT. Carefully snug it tight to just past finger tight. When you are done and all assembly is complete you will have to fill the fuel tank with the sending unit installed (The sending unit will have to be checked for cracked lines a
where they enter the top) then syphon out the gas and refill the tank. If you did everything right then it will work. You must fill, syphon and refill to pressurize the system.
I am not a member of the REO club but I own the other ‘29 REO May Car Of The Month. Good Luck to anyone who performs this rebuild. It is worth it. Regards J.B.

From there he was able to mechanically work the gunk out of the tubes with fine wire and a hypodermic needle. Now is a good time to chase the threads on the hex tube. You will need to measure the thread count and order the right die. I think we had to grind down the die to be able to use it in such a tight space. After he was satisfied that it was clean he then resoldered it back together and tested it by blowing through it.

When you are done and all assembly is complete you will have to fill the fuel tank with the sending unit installed (The sending unit will have to be checked for cracked lines where they enter at the top of the sending unit and for pinholes in the tubes and the little cups must be pinhole free and securely attached) then syphon out the gas and refill the tank. If you did everything right then it will work. Don’t forget, you must fill, syphon and refill the fuel tank to pressurize the system.
