    OEM Toyota fuel gauge resistance:

    Full = 17 +/- 2.1 ohms
    Half = 40 +/- 4.5 ohms
    Empty = 120 +/- 6.5 ohms

    just for interests sake, these are the readings I got from my 74. They could be wrong, but seem to correspond to the overall level. (IE: reads full after I fill it from the pump, fill the correct gallons at 1/2 - 1/4 full)
    I took them after a rebuild and I was sure it was empty. The "5.8" and "11.6" are exactly what I put in after re-installation...

    174.2 ohms empty
    67 ohms 5.8 gal
    33.2 ohms 11.6 gal

    HTH!
