Should I use my original sending unit in new gas tank or replace it with a new one. Some say the new units won't read correctly?? I have a new one purchased from Spectra, but still have my original also.
That reminds me of my first car, a 69 Ford Fairlane that had been rear ended. It had a 10gal. tank with a 20 gal. sender, the gauge read from 1/4 - 3/4's.I'm with the "if it's not broke don't fix it", but there is a lot you can compare between the new one and the original. Get a ohmmeter and compare total resistance between the two and the difference in resistance at the different angles of the arm. Also compare the shape of the two to make sure they are actually shaped the same. My original in my 70 Bird was not able to be saved therefore I have spent endless hours trying to make the new one accurate. The best I have been able to do is get it where I have about a gallon left when it shows E, and when the tank is completely full the gauge shows about a needle width below F. If I make it show F it will run out of gas before E. The cluster was professionally done and calibrated by Redline Gauges and there is nothing wrong there.
Are they all Shinese made? I’m working with a scalable EFI system so I can program the full and empty readings.Original all they way.......reproductions are junk

numerous threads out there concerning the new lock rings furnished with the new tanks that are not thick enough.
