    I put a fuel cell in my hotrod that has a GM sending unit. How do I make it read on my ford gauge?
    Thanks in advance!!
     
  2. The have different OH
    • Ford up to 1986 - 73-10 Ohms
    • Ford 1987 & up - 16-158 Ohms
    • GM up to 1964 - 0-30 Ohms
    • GM 1965-1997 - 0-90 Ohms
    • GM 1998 & up - 40-250 Ohms
    • Mopar up to 1986 - 73-10 Ohms
    • AMC 1950-1977 - 73-10 Ohms
    • Autometer -240-33 Ohms is the most common however other ohm ranges are made
    • Cl***ic Instruments - 240-33 Ohms (excluding vehicle specific gauge kits which use factory ohm range)
    • Dolphin - 0-90 Ohms
    • Dakota Digital - Programmable to work with most Ohm range senders
    • VDO - 10-180 Ohm
    M ratings. Probably have to change the sending unit to match the gauge.

    This is kinda backwards from what you have but Autometer was able to swap out a new gauge internals to match my new old Pontiac sender (0 - 30 ohms).

    I am not sure what is actually in my cell. It was just advertised as a GM sending unit.

    That will mean late-GM, 0-90 ohms. I have never seen new-GM one on a universal cell.

    You should seek out a different sender.
